Unit 3 Heat Review

Front

What happens to the kinetic energy at interval AB?

Back

The kinetic energy is increasing.

Front

What happens to the kinetic energy at interval BC?

Back

The kinetic energy is staying constant.

Front

How much heat is required to completely vaporize a 37 gram sample of water at its boiling point of 100°C?

Back

83,620 J.

Front

When temperature increases, what happens to kinetic energy?

Back

The kinetic energy increases.

Front

What is the definition of heat?

Back

Heat is the energy transferred between systems or objects with different temperatures (flowing from hot to cold).

Front

What is the specific heat capacity of water?

Back

The specific heat capacity of water is 4.18 J/g°C.

Front

What is the formula for calculating heat energy (Q)?

Back

Q = mcΔT, where m is mass, c is specific heat capacity, and ΔT is the change in temperature.

Front

What is latent heat?

Back

Latent heat is the heat required to change the state of a substance without changing its temperature.

Front

What is the latent heat of vaporization for water?

Back

The latent heat of vaporization for water is approximately 2260 J/g.

Front

What is the difference between conduction, convection, and radiation?

Back

Conduction is heat transfer through direct contact, convection is heat transfer through fluid movement, and radiation is heat transfer through electromagnetic waves.
