Back

B-C.

Front

For a skillet used for cooking, do you want a high or low specific heat?

Back

Low, so that it will change temperature quickly.

Front

What is activation energy?

Back

The minimum energy required to initiate a chemical reaction.

Front

What is specific heat?

Back

The amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.

Front

What is the formula for calculating energy change?

Back

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

Front

What is thermal equilibrium?

Back

The state in which two bodies in contact with each other exchange no heat energy.

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred between objects, while temperature is a measure of the average kinetic energy of particles.

Front

What is the significance of the heat capacity of a substance?

Back

It indicates how much heat energy is needed to change the temperature of a substance.
