A 75 gram sample of water is initially at 30 degrees Celsius. What would it's temperature be if
it absorbed 2000 J of heat?
Answers
Answer:
T2 = 36.38°C
Explanation:
Given data:
Mass of water = 75 g
Initial temperature = 30 °C
Final temperature = ?
Heat absorbed = 2000 J
Solution:
Specific heat capacity of water is 4.18 J/g.°C
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = Final temperature - initial temperature
2000 J = 75 g×4.18 J/g.°C × T2- T1
2000 J = 313.5 J/°C × T2- T1
2000 J = 313.5 J/°C × T2 - 30 °C
2000 J / 313.5 J/°C = T2 - 30 °C
6.38 °C = T2 - 30 °C
T2 = 6.38 °C + 30°C
T2 = 36.38°C

A process that releases heat, such as freezing or condensation is called?
Answers
Answer:
exothermic
Explanation:
An exothermic reaction gives off heat energy. Condensation is the process by which water vapor turns into liquid water. This typically occurs when water vapor molecules come into contact with cooler molecules. This causes the water vapor molecules to lose some energy as heat which is a exothermic reaction.
When water becomes a solid, it releases heat, warming up its surroundings. This makes freezing an exothermic reaction.

Find the mass of 1.25 moles Ca(OH)2.
Answers
92.5
Explanation
1.25 x 74= 92.5g
According to the mole concept, the mass of 1.25 moles Ca(OH)₂ is 92.61 grams.
What is a mole?Mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.
It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.
It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons. Molar mass has units of gram per mole . In case of molecules, where molar mass in grams present in one mole of atoms is its atomic mass.Mass=number of moles×molar mass=1.25×74.09=92.61 g.
Thus,the mass of 1.25 moles Ca(OH)₂ is 92.61 grams.

Answer:
Answer is C. liquid water.
Explanation:
I hope it's helpful!
Liquid water has the highest density. Therefore, the correct option is option C among all the given options.
What is density?The density of a substance is defined just like its weight per unit volume. In other words, density is the mass-to-volume ratio or mass for every unit volume. It quantifies how much "stuff" a thing possesses in an unit volume (cubic meter or cubic centimeter).
Density is a measure of how closely stuff is packed together. The density principle was established by the Greek scholar Archimedes, which is simple to compute if one know the equation and its associated units. Lquid water has the highest density.
Therefore, the correct option is option C among all the given options.

Both freezing and melting decrease salinity.
Freezing decreases salinity, while melting increases salinity.
Both freezing and melting increase salinity.
Answers
Answer:
For every 5 psu increase in salinity, the freezing point decreases by 0.28 degrees Celsius (0.5 degrees Fahrenheit); thus, in polar regions with an ocean salinity of about 32 psu, the water begins to freeze at -1.8 degrees Celsius (28.8 degrees Fahrenheit).
