Thermal Energy

Which increases the kinetic energy of the particles that make up a bowl of soup?

• Dividing the soup in half

• Putting the soup in a refrigerator

• heating the soup for 1 min on a stove

• decreasing the distance between the particles that make up the soup

The transfer of thermal energy from one material to another by electromagnetic waves is called radiation.

• True

• False

What energy is the energy of heat, which transfers from hotter objects to colder objects? This energy comes from the motion of atoms and molecules. The faster the particles in an object move, the more ________ energy is produced.

• Kinetic

• Radiant

• Thermal

• Chemical

The total kinetic energy of the tiny particles that make up matter.

• Thermal Energy

• Energy Transfer

• Temperature

• Heat

This type of thermal energy transfer can take place in solids, liquids, & gases when two objects are touching.

• conduction

• convection

• radiation

This type of thermal energy transfer can take place in fluids (liquids & gases). Rising of warmer fluid and sinking of cooler fluid forms a current.
