This measures how hot or how cold a material is

• Temperature

• Heat

• Thermometer

Which of the following statements is true?

• The faster the particles move, the lower the temperature.

• The faster the particles move, the higher the temperature.

• The slower the particles move, the higher the temperature.

This is an instrument that measures temperature

• Thermometer

• Heat

• Temperature

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.

If two objects have different temperatures, heat will flow from the warmer object to the cooler one UNTIL ____________

• one reaches a temperature of zero

• they both have an equal temperature

• one runs out of energy

Heat is the _______ of energy.

• Transfer
• Measure

Temperature is the ________ of energy.

• Transfer
• Measure

Lisa has a bottle of water. How can she increase the thermal energy of the water?

• She can pour the water into a larger bottle.

• She can increase the temperature of the water.

• She can place the bottle of water in the refrigerator.

• She can divide the water between tow identical containers.

How does heat affect the thermal energy of an object that is colder than the air that surrounds it?

• Heat decreases the thermal energy of an object as energy moves to the air.

• Heat causes the thermal energy of the object to increase as energy moves from the warmer air to the colder object.

• Heat has no effect on thermal energy, but it increases the potential energy of an object.

• Heat is not related to thermal energy, so it cannot affect the thermal energy of an object.
