Answer:

P₂ = 1.37

Explanation:

Given data:

Initial pressure = 1.15 atm

Initial temperature = 23°C (23+273= 296 K)

Final pressure = ?

Final temperature = 79°C (79+273=352 K)

Solution:

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

1.15 atm / 296 K = P₂/352 K

P₂ = 1.15 atm × 352 K / 296 K

P₂ = 404.8 atm. K /296 K

P₂ = 1.37 atm

Answer:

Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there. first question Natural non-living things: They are found in nature and are not made by man. Examples: Sun, moon, stars, sky, clouds, rocks, mountains and many more. Man-made non-living things: They are made by man. Examples: Toys, chairs, tables, beds, houses, buildings, trains and many more. second question Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock. The parent rock can be either sedimentary, igneous, or even another metamorphic rock. The word "metamorphic" comes from Greek and means "To Change Form". third question.

Explanation:

F = GMm/R²

The magnitude of attractive forces between particles that compose matter determine the state of matter. Hence, if all particles of matter on earth have equal attractive forces, only a single state of matter (solid, liquid or gas) will exist on earth.

Matter exists in three states;

In solids, there exists the greatest magnitude of attractive forces between particles.

There are weaker inter-molecular attractive forces between liquid particles. However, inter molecular attractive  forces are almost non-existent in gases.

The reason for the existence of different states of matter on earth is difference in magnitude of inter molecular attractive forces in each state of matter.

If all particles of matter possess equal attractive forces, only one state of matter will be found on earth; either solid, liquid or gas.

Answer:

Ag > Fe > Al

Explanation:

The values of the specific heat capacity of the elements are given as;

Aluminum = 0.897 J/g*K  

Iron=0.449 J/g*K  

Silver=0.235 J/g*K

Specific heat capacity basically refers to how much heat is required to change the temperature of a unit mass of a substance by a degree. Elements with high specific heat capacity would require higher energy compared to elements with lower values,

Aluminium (Al) has the highest specific heat capacity, hence it wold require more energy to cause a change in temperature. Aluminium would be the lowest.

Silver (Ag) has the lowest specific heat capacity hence it would require less energy to cause a change in temperature. Silver wold be the highest.

The middle would be iron (Fe).

The rank is given as;

Ag > Fe > Al

Answer:

kinectic is movement and potential is still

Explanation:

While kinetic energy of an object is relative to the state of other objects in its environment, potential energy is completely independent of its environment. Hence the acceleration of an object is not evident in the movement of one object, where other objects in the same environment are also in motion.

Answer:an object’s speed

Density is a value for mass, such as kg, divided by a value for volume, such as m3. Density is a physical property of a substance that represents the mass of that substance per unit volume. It is a property that can be used to describe a substance. We calculate as follows:

Volume = 60.0 g ( 1 mL / 0.70 g ) = 85.71 mL

Therefore, the correct answer is option B.

Explanation:

888 grams is a mass of ether that the bottle can hold.

Explanation:

The density of the substance is defined as a mass of substance present in the unit volume of the substance.

[tex]Density=\frac{Mass}{Volume}[/tex]

Given:

A bottle with a capacity of 1.2 Liters.

The density of ether = 0.74 g/mL

To find:

The mass of ether hold by a given bottle.

Solution:

The volume of bottle = V = 1.2 L

[tex]1 L = 1000 mL\\V = 1.2 L=1.2\times 1000 mL= 1200 mL[/tex]

The density of the ether = d = 0.74 g/mL

The mass of ether that bottle can hold = m

Volume of ether required = Volume of bottle = V = 1200 mL

Using the formula of density:

[tex]d=\frac{m}{V}\\0.74 g/mL=\frac{m}{1200 mL}\\m=0.74 g/mL\times 1200 mL= 888 g[/tex]

888 grams is a mass of ether that the bottle can hold.

Explanation:

In an ecosystem, organisms feed on one another for survival due to the fact that energy needed for metabolic activities in individual organisms can only be obtained via food. This question depicts that certain bird population feeds on barley plant in an ecosystem.

However, If a disease attacks the plants in such a way that it destroys the barley plants in the field, this would cause the barley-eating bird population to DECREASE because their food source has been affected.

Answer:

10 g H₂SO₄

General Formulas and Concepts:

Chemistry - Stoichiometry

Explanation:

Step 1: Define

Given:   8 g SO₃

RxN:   SO₃ + H₂O → H₂SO₄

Step 2: Identify Conversions

Molar Mass of S - 32.07 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of H - 1.01 g/mol

Molar Mass of SO₃ - 32.07 + 3(16.00) = 80.07 g/mol

Molar mass of H₂SO₄ - 2(1.01) + 32.07 + 4(16.00) = 98.09 g/mol

Step 3: Stoichiometry

[tex]8 \ g \ SO_3(\frac{1 \ mol \ SO_3}{80.07 \ g \ SO_3} )(\frac{1 \ mol \ H_2SO_4}{1 \ mol \ SO_3} )(\frac{98.09 \ g \ H_2SO_4}{1 \ mol \ H_2SO_4} )[/tex] = 9.80042 g H₂SO₄

Answer:

The final temperature is 566°K

Explanation:

Given

V1 = 0.444L

T1 = 0.00°C

P1 = 79.00 kPa

V2 = 1880mL

P2 = 38.70 kPa

Required

Determine the final temperature of the gas

To answer this, we make use of idea gas law equation.

This is:

(P1V1)/T1 = (P2V2)/T2

Convert V1 to mL

V1 = 0.444L

V1 = 0.444 * 1000mL

V1 = 444mL

Convert T1 to Kelvin

T1 = 0.00°C

T1 = 0.00 + 273K

T1 = 273K

Substitute these values in the given equation.

(P1V1)/T1 = (P2V2)/T2

(79 * 444)/273 = (38.70 * 1880)/T2

35076/273 = 72756/T2

Cross Multiply

35076 * T2 = 273 * 72756

35076T2 = 19862388

Make T2 the subject

T2 = 19862388 ÷ 35076

T2 = 566K (approximated)

Hence, the final temperature is 566°K

Answer:

0.303kg/m

Explanation:

Density=m/v where m is mass

and v is volume

we then convert m in grams to kg

converting ml to m

=11.3/100

=0.113m

then density=0.0342/0.113

=0.303kg/m
