Heat Capacity

[Sofia Ban]

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

[MinuChoi]

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.

[Bryce Ramirez 1J]

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?

[Natalie Benitez 1E]

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

[MinuChoi]

How do we know the heat capacity?

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

[Kavya Immadisetty 2B]

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

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?

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.
