Thermal Equilibrium

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in thermal contact no longer exchange heat, meaning they are at the same temperature.

Front

What happens to the temperature of a substance when it gains thermal energy?

Back

The temperature of the substance increases as the molecules move faster.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is an example of conduction in everyday life?

Back

Ironing a shirt is an example of conduction.

Front

What is the relationship between temperature and molecular motion?

Back

Higher temperatures correspond to faster molecular motion, while lower temperatures correspond to slower molecular motion.

Front

What is the significance of thermal energy in all matter?

Back

All matter contains thermal energy, which is the energy associated with the random motion of particles.

Front

What is the primary mode of heat transfer in solids?

Back

Conduction is the primary mode of heat transfer in solids.

Front

How does warm air behave compared to cool air?

Back

Warm air rises because it is less dense than cool air, which sinks.

Front

What is the role of physical contact in conduction?

Back

Conduction can only occur between two objects when they are in physical contact with each other.
