A teacher tells the student to dlaw the same wave with double the frequency, while keeping the amplitude the same. How would the student draw the new wave?
Answers
Answer:
A.
Explanation:
Frequency is how often one complete cycle or wave takes place. Amplitude is the height of the wave from the midpoint to the crest.

When a 8 gram slice of bread is burned under a beaker of 4500 grams of water, it heats up the water by 1.3 degrees Celsius. The specific heat of water is 1 cal/g degree C. How many calories does this slice of bread contain
Answers
Answer:
[tex]5850\ \text{cal}[/tex]
Explanation:
m = Mass of water = 4500 g
c = Specific heat of water = [tex]1\ \text{cal/g}^{\circ}\text{C}[/tex]
[tex]\Delta T[/tex] = Change in temperature of water = [tex]1.3^{\circ}\text{C}[/tex]
Heat is given by
[tex]q=mc\Delta T\\\Rightarrow q=4500\times 1\times 1.3\\\Rightarrow q=5850\ \text{cal}[/tex]
A slice of the bread contains [tex]5850\ \text{cal}[/tex].

Which is NOT an assumption of matter made by the kinetic molecular theory of gases?
a. The kinetic energy of particles is determined by their mass and their velocity.
b. Gas particles are widely dispersed and therefore are not affected significantly by attractive or repulsive forces.
c. Gas particles are small and take up little volume relative to the volume of the space around them.
d. When particles collide, their total energy is decreased.
Answers
Answer:
There is strong attraction or repulsion between the gas particles.In other words,they strongly interact with each other" is NOT an assumption made by kinetic molecular theory.
The theory that attempts to elucidate the behaviour of gases is known as kinetic molecular theory.
The postulates of kinetic molecular theory of gases are given below,
\bigstarGases consist of large number of identical particles(atoms or moleculesthat are so small and so far apart
\bigstar There is no force of attraction between the particles of a gas at ordinary temperature and pressure
\bigstarParticles of a gas are always in constant and random motion
\bigstarParticles of a gas move in all possible directions in straight lines. During their random motion, they collide with each other and with the walls of the container
\bigstarCollisions of gas molecules are perfectly elastic. This means that total energy of molecules before and after the collision remains same
\bigstarThe average kinetic energy (energy due to motion) of the gas particles is proportional to the temperature measured in kelvin. As temperature increases, the particles move faster and have more energy
\bigstarAt any particular time, different particles in the gas have different speeds and hence different kinetic energies.
\therefore From the above data it is clear that "There is strong attraction or repulsion between the gas particles.In other words,they strongly interact with each other" is NOT an assumption made by kinetic molecular theory.
Explanation:
According to Kinetic theory of gases, the kinetic energy of particles are derived from the temperature and not by their mass and velocity. Hence, option a is not an assumption of kinetic theory of gases.
What is kinetic theory gases ?According to kinetic theory of gases, gases substances are made of tiny particles. These particles when taken in a container have negligible volume compared to the volume of the container.
The collision between the gaseous particles and and between the particles and the wall make the pressure within the container. The kinetic energy of the particles is directly proportional to the temperature of the gas.
According to the theory, the kinetic energy is not determined from the mass and velocity of the particles, but by the temperature of the system. Hence, option a is not an assumption of kinetic molecular theory of gases.

Calculate the change in heat (Q) that occurs when 7.58grams of steam at 101°C cools to liquid water at 40°C. (cp = 4.184 J/g°C)
Answers
Answer:
Q = 19065.4 J
Explanation:
Q₁ = the required energy for phase change of H₂O from vapor to liquid
Q₁ = mass of H₂O * heat of vaporization
Q₁ = 7.58 g * 2260 J/g
Q₁ = 17130.8 J
Q₂ = energy required to cool the water fro 101°C to 40°C
Q₂ = mass of H₂O * specific heat of H₂O * ΔT
Q₂ = 7.58 × (4.184 J/gC) × (101 - 40)
Q₂ = 1934.6 J
Q = Q₁ + Q₂
Q = (17130.8 + 1934.6) J
Q = 19065.4 J

The teacher asked the students to design an experiment that would demonstrate that temperature will affect the pressure of a gas. Which of the
following would be a valid experiment that shows the correct relationship between gas temperature and pressure?
Answers
The correct option is option A. when the students check the air pressure of bicycle tires, once by keeping it out in the winter and noticing the air pressure being decreased and after by keeping the bicycle inside at room temperature and noticing that the air pressure has increased.
How are pressure and temperature of a gas related ?
According to Gay lussac's law, the temperature and pressure of a gas are directly proportional to each other, provided the volume is constant.
When the temperature of a gas is increased, the molecules gain more kinetic energy and hence the frequency of them hitting the walls of the container increases which basically implies that the pressure increases.
On the other hand when the temperature is low, the molecules do not have substantial kinetic energy to hit the walls of the container frequently, that is the pressure decreases.
When the bicycle tires were kept out in the winter, the low temperature decreased the air pressure inside the tires. While when they were warmed at room temperature, the pressure inside the tires increased.
Therefore, the correct option is option A. when the students check the air pressure of bicycle tires, once by keeping it out in the winter and noticing the air pressure being decreased and after by keeping the bicycle inside at room temperature and noticing that the air pressure has increased.

(atomic mass: C = 12.01, H = 1.01, 0 = 15.99)

Answer:
62.00
Explanation:
H2 means that there are two moles of hydrogen so multiply the atomic mass by two (1.01 × 2 = 2.02)
C only has one mole sp leave 12.01 alone
And multiply oxygen by 3 because there are three moles of oxygen (15.99 × 3 = 47.97)
Add them all together!
2.02 + 12.01 + 47.97 = 62.00 for molar mass

Answers
Hello! Here's the answer I was able to come up with:
Why does Na have only one dot?
Sodium, or Na, has only one valence electron. (This makes the atom tend to participate in ionic bonding and "give" its single valence electron to an atom like chlorine.)
Why do none of these diagrams show more than 8 dots?
It is physically impossible for an atom to have more than 8 electrons in its valence layer, according to the Octet Rule.
What relationship do you notice between the dots in these two charts?
The dot diagram for each element represents the number of electrons each element will have in its outermost, or valence, shell. (2-8-8)
The number of dots that hydrogen and helium have in their dot diagram is the same as the number of electrons shown for them on the Periodic Table. Why?
An atom can have a maximum of two electrons in its innermost layer. Hydrogen and helium have only one and two electrons, respectively, so they don't have enough electrons to actually have more than one layer. Therefore, their outermost layer is, in fact, their only layer. This is why the number of dots that hydrogen and helium have in their dot diagram is the same as the number of electrons shown for them on the Periodic Table.
