Thermal Equilibrium (7.8B)

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature, resulting in no net heat transfer between them.

What is the purpose of insulation in a house?

Back

To minimize heat transfer, keeping the house warm in winter and cool in summer.

What happens to the temperature of a hot object when placed in a cooler environment?

Back

The temperature of the hot object decreases as it loses thermal energy to the cooler environment.

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What occurs when thermal energy moves from a warmer object to a cooler object?

Back

Heat transfer occurs, leading to a decrease in temperature of the warmer object and an increase in temperature of the cooler object.

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

Back

Specific heat capacity is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius, indicating how much energy a substance can store.

What is the role of thermometers in measuring temperature?

Back

Thermometers measure the temperature of a substance by indicating the average kinetic energy of its particles.

Front

What happens to particle motion in a solid as it heats up?

Back

As a solid heats up, its particles gain energy and vibrate more rapidly, leading to an increase in temperature.
