Amplify Thermal Energy C2 Flashcard

Front

What happens when a frozen Bubba-Burger is placed on a hot grill?

Back

The grill molecules are transferring energy to the Bubba-Burger.

Front

How do the molecules of an object behave when it gets colder?

Back

The molecules move slower.

Front

True or False: When two objects collide, the warmer one always transfers its energy to the cooler one.

Back

True.

Front

If a 40-degree cup of coffee and a 90-degree cup of coffee sit out on a 30-degree day, which will likely be warmest after 10 minutes?

Back

The 90-degree cup because it transferred energy to the colder air.

Front

What is absolute zero?

Back

Absolute zero is when molecules have zero molecular movement.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the molecules in an object.

Front

What is the principle of energy transfer between objects?

Back

Energy transfers from warmer objects to cooler objects until thermal equilibrium is reached.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact no longer transfer energy to each other.

Front

What happens to the energy of a hot object when it is placed in a cooler environment?

Back

The hot object loses energy to the cooler environment.

Front

What is conduction?

Back

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