Heat and temperature review

Heat is a form of energy that

• moves from cooler to warmer objects

• moves from warmer to cooler objects

• the temperature on a hot day

• the temperature of a hot object

_________________________ is a measure of the average kinetic energy of the particles in a material.

• thermal
• friction
• temperature
• expansion

The most common temperature scale used in Australia, in which water freezes at 0 degrees and boils at 100 degrees is called the __________________________ scale.

• Celsius

• Pound

• Kelvin

• Fahrenheit

An increase in the volume of a substance when the temperature increases is called ___________________________________.

• kinetic energy
• thermal expansion
• temperature
• heat

When two objects are at the same temperature they are in thermal equilibrium

• True

• False

Which of the following containers of sand has atoms/molecules with the greatest average kinetic energy?

• 1 kg at 20^oC

• 2 kg at 20^oC

• 4 kg at 20^oC

• all have the same temperature and therefore the same average kinetic energy

Temperature is a measure of

• how much total kinetic energy the particles in an object contain

• how much energy an object can transfer

• how "hot" or "cold" an object is

• All of the above

How does heat transfer when you hold an ice cube in your hand?

• from the cold ice cube to your warm hand

• the cold ice cube makes your hand cold

• from your warm hand to the cold ice cube

• very carefully

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

• More rapidly at an increased distance from each other

• More rapidly with less distance between each other

• More slowly with a greater distance between each other

• More slowly with less distance between each other

An object in which molecules are moving faster than those in another object

• has a higher temperature

• has a lower temperature

• both are in thermal equilibrium

• both have the same internal temperature
