• temperature

• condensation

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.

Which of the following describes a way in which heat energy will be transferred by conduction?

• Sample 1 to Sample 2
• Sample 3 to Sample 2
• Sample 3 to Sample 1
• Sample 2 to Sample 3

Which of following is a conductor?

• Wooden Stick
• Styrofoam Cooler
• Metal Pot
• Plastic Container

Heat transfer occurs:

• in many directions
• both from warm objects to colder ones and from cold objects to warmer ones
• only from warm objects to colder ones
• only from cold objects to warmer ones

When you touch something that feels cold, 

• heat from your hand moves into the cold substance.
• coldness moves from the cold substance into your hand.
• it melts.
• it freezes.

The temperature of a substance increases as___.

• the substance expands
• the average kinetic energy of its particles increases
• the substance's volume increases
• the substance's mass increases
