ThermoChem Review

Front

What is thermal equilibrium?

Back

Thermal equilibrium is reached when the temperature difference between two systems is zero.

Front

What happens to the temperature of a substance as the kinetic motion of its molecules decreases?

Back

The temperature of the substance decreases.

Front

What is the term for the energy transferred between samples of matter due to a temperature difference?

Back

Heat.

Front

How much energy (Q) is required to heat up 1200 g of copper from 10 °C to 120 °C if the specific heat capacity is 0.390 J/g °C?

Back

514800 J.

Front

What is the process called when a pot gets hot on a stove?

Back

Conduction.

Front

Define specific heat capacity.

Back

Specific heat capacity is the amount of heat required to raise the temperature of 1 gram of a substance by 1 °C.

Front

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

Back

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

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself.

Front

What is convection?

Back

Convection is the transfer of heat by the physical movement of fluid (liquid or gas).

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves.
