Thermal Equilibrium (7.8B)

Front

What occurs when thermal equilibrium is reached within a system?

Back

All substances within the system have the same temperature.

Front

How does thermal energy move in a closed system until thermal equilibrium is reached?

Back

It moves from warmer to cooler areas until equilibrium.

Front

If you heat one end of a metal rod, how does the thermal energy move through the rod to reach thermal equilibrium?

Back

Through a combination of conduction and convection.

Front

What term describes the transfer of thermal energy from warmer objects to cooler objects when they come into contact?

Back

Conduction

Front

If you place a hot cup of coffee on a cold kitchen counter, which process allows the coffee to cool down as it transfers heat to the counter?

Back

Conduction

Front

In a closed room with a hot radiator, how does the thermal energy move to reach equilibrium within the room?

Back

Through convection

Front

In a well-insulated house on a hot summer day, what happens to the thermal energy inside the house?

Back

It moves from warmer rooms to cooler rooms until equilibrium is reached.

Front

How does thermal energy transfer occur when an ice cube is placed in warm water?

Back

Through a combination of conduction and convection.

Front

What is the purpose of insulation in a house in terms of thermal energy transfer?

Back

To minimize heat transfer.

Front

If you added a can of Coke (20^oC) to a fridge (5^oC), at what temperature would heat stop moving?

Back

When the coke is at at 6 degrees and the fridge is at 6 degrees
