How are CP and CV related?

So, Cp represents the molar heat capacity, C when pressure is constant. Cv represents the molar heat capacity C when volume is constant. Under a constant volume, the volume of a substance does not change, so the change in volume is zero.

Why do liquids have higher heat capacity than solids?

liquid has a higher heat capacity than solid or gas and this is because liquid can absorb the most heat (translational and vibrational) but solids absorb only vibrational and gases absorb only translational. On heating a liquid, its temperature increased from 40°C to 50°C.

What liquid has the highest heat capacity?


What is heat capacity of solids?

Heat capacity or thermal capacity is a physical property of matter, defined as the amount of heat to be supplied to a given mass of a material to produce a unit change in its temperature.

Which phase has the highest specific heat?

Liquid water

What is the most heat absorbing material?

Zeolite thermal storage retains heat indefinitely, absorbs four times more heat than water.

Why is steam so hot?

The higher the pressure, the higher the boiling temperature and the higher the heat content. If pressure is reduced, a certain amount of sensible heat is released. This excess heat will be absorbed in the form of latent heat, causing part of the water to “flash” into steam.

What is the specific heat of water in kJ?

The specific heat of liquid water is 4.184 J/g, which is also 4.184 KJ/Kg. The calorie is a unit of heat defined as the amount of heat required to raise the temperature of 1 cm3 of water by 1˚C.

What is C in Q MC?

Q=mcΔT Q = mc Δ T , where Q is the symbol for heat transfer, m is the mass of the substance, and ΔT is the change in temperature. The symbol c stands for specific heat and depends on the material and phase. The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00ºC.
