### Heat Capacity

What is the relationship between high/low heat capacity and overall transfer of energy?

### Re: Heat Capacity

Substances with higher heat capacity require more energy to raise its temperature and will have to expend more energy to cool down.
If you're referring to heat transfer between two substances, the substance with a higher heat capacity will experience a smaller change in temperature because more energy transfer is required to change its temperature.

### Re: Heat Capacity

Lower heat capacity means that the substance will easily heat and cool. Heat transfer will also easily happen when the value for the heat capacity is low.

The book states that "The constant-volume and constant-pressure heat capacities of a solid substance are similar; the same is true of a liquid but not of a gas". Why is this not true for a gas?

### Re: Heat Capacity

How do we know the heat capacity also how does heat transfer of energy work?

There's a formula for calculating it given heat and temperature (textbook p. 251). For specific heat capacities, those are unique for every substance.

High heat capacity means that more energy is taken to increase or decrease the overall temperature.

I'm curious about this as well because in lecture he said you need to specify these different heat capacities for gases only, but I didn't really understand why.
