1.3 Heat and Temperature

Front

What is the transfer of thermal energy between objects of different temperatures called?

Back

Heat

Front

What happens to the kinetic energy of an object as it gets hotter?

Back

It has more kinetic energy.

Front

According to the Law of Thermodynamics, thermal energy moves from __________ to __________.

Back

Hottest to coolest.

Front

When does an object stop transferring heat in a room temperature environment?

Back

When it has reached the same temperature as the room temperature air.

Front

What happens when two metal cubes touch each other and have different temperatures?

Back

Energy will transfer from the hottest to the coolest cube until they're the same temperature.

Front

What is temperature a measure of?

Back

The average kinetic energy of the particles in an object.

Front

What is thermal equilibrium?

Back

A state where two objects in contact no longer transfer heat because they are at the same temperature.

Front

What is the relationship between heat and temperature?

Back

Heat is the energy transferred due to temperature differences, while temperature measures how hot or cold an object is.

Front

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

Back

It loses thermal energy to the cooler environment.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.
