A barefoot student steps on a hot concrete surface. Most of the heat transferred to the student’s skin by this contact is by the process of—

• convection
• conduction
• vaporization
• radiation

The total energy of all the particles in a sample of matter is called —————

• Total Energy

• Thermal Energy

• Kinetic Energy

• Particle Energy

the average kinetic energy of the particles in iced tea is —————than the average kinetic energy of the particles in hot tea.

• louder

• Prettier

• Higher

• Lower

Thermal energy is transferred from————-

• A cooler object to a hotter one

• A hotter object to a cooler one

Conduction can only occur between two objects when –

• one object is less dense than the other.
• both objects are in physical contact with each other.
• one of the objects is made of a metal.
• both objects are exactly the same temperature.

Heat will always transfer from the ___________ object to the ________ object.

• The hottest object to the coolest object.

• The coolest object to the hottest object.

• The solid object to the liquid object.

• The liquid object to the solid object.

The sun warming your skin is an example of heat transfer through 

• conduction
• convection
• radiation
• thermal electricity

The transfer of thermal energy between objects of different temperatures is called...

• temperature
• heat
• internal energy
• none of these

When thermal energy is added to a substance, the substance's particles move:

• More rapidly at an increased diestance from each other.
• More rapidly with less distance between each other.
• More slowly with a greater distance between each other.
• More slowly with a reduced distance between each other.

What is a transfer of heat energy by electromagnetic waves?

• Radiation
• Convection
• Conduction
• Heat
