Heat and Thermal Energy 2023

Front

What is convection?

Back

The transfer of thermal energy when particles of a fluid move from one place to another.

Front

How does heat transfer occur?

Back

Heat transfer occurs only from warm objects to colder ones.

Front

Which cup has the most thermal energy if all are at the same temperature?

Back

The large cup (Trenta) has the most thermal energy.

Front

Which material would be coolest after being heated: Copper, Carbon Steel, Zinc, or Stainless Steel?

Back

Carbon Steel would be the coolest after being heated.

Front

True or False: When heat is absorbed by an object, the speed of the particles in the object is unchanged.

Back

False.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in a substance.

Front

What is conduction?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves.

Front

What happens to particle speed when heat is added?

Back

The speed of the particles increases when heat is added.

Front

What is the relationship between temperature and thermal energy?

Back

As temperature increases, thermal energy also increases.
