Heat is thermal energy transferred from one object to another because of a difference in _____

Most materials _____ when they are heated.

Thermostats transform thermal energy into _____ energy.

A liquid thermometer works because liquid _____ when warmed.

A part of a refrigerator that compresses the coolant and increases its thermal energy is called a _____

The thermal energy of an object is its kinetic energy plus its _____ energy.

The transfer of warmth from the water bottle to feet is an example of _____

A curling iron, coffeemaker, and clothes iron are examples of a _____ appliance.

The part of an internal combustion engine where the gasoline is mixed with air is called the _____

A bimetallic coil is used in a thermostat because the two materials heat and cool at different _____

A heat engine changes thermal energy into _____ energy.

The part of a refrigerator that removes thermal energy from inside the refrigerator is the _____ vapor.

Temperature is a measure of the average _____ energy of particles in an object.

The part of a refrigerator that causes the coolant to change from a liquid to a gas is the _____ valve.

The lowest possible temperature is _____ K.

The mechanical energy of a football during a pass is its potential and _____ energy.

Which part of the internal combustion engine transforms thermal into mechanical energy? The _____

Heat is thermal energy that is transferred from one object at a certain temperature to another at a different _____

When temperature increases, average _____ energy increases.

A toaster has a temperature regulator called a _____

Objects that are at the same temperature can only have different _____ energies.

In an automobile engine, the fuel burns in a _____ chamber cylinder inside the engine.

Heat always moves from _____ objects to _____ objects.

Refrigerators work by transferring thermal energy out of the refrigerator into the _____

The three temperature scales that are used today are the Fahrenheit scale, Celsius scale, and the _____ scale.

A heat engine is used to drive a steam locomotive and run an _____

A device used to iron clothes is a _____ appliance.

A refrigerator keeps food cool and cools a house in the _____

A device that keeps a toaster from overheating is a _____

How does thermal energy interact with the coolant in a refrigerator? The coolant, which begins as a liquid, passes through a valve where it changes into a gas and becomes _____

Briefly explain how a bimetallic coil can act as a switch to turn off the furnace. A bimetallic coil is made of two types of metal joined together and bent into a coil. The metal on the inside of the coil expands and contracts more than the metal on the outside. After the room warms, thermal energy from the air moves to the coil and causes it to _____ slightly, moving a switch that turns off the furnace.

Can an object obtain heat? Why or why not? No, heat is thermal energy, but it is only energy being transferred between two _____

When ice melts from a pond in the spring, what happens to the air above it? The air above the ice is cooled because melting requires energy taken from the _____

Picture an iceberg and a hot cup of tea. Compare the thermal energy and the kinetic energy of the two particles. The thermal energy is greater in the iceberg because of its mass, while the kinetic energy is greater in the hot tea because of its _____

Identify three scales that are used to measure temperature, then compare and contrast temperature and thermal energy by identifying the way they are similar and the ways they are different. Explain why a thermometer does not measure thermal energy. There are three scales used to measure temperature: Kelvin, Fahrenheit, and Celsius. Temperature and thermal energy are similar in that they are related to the energy of the particles of objects. Temperature is a measure of the total energy (potential and kinetic) of all the particles in an object. A thermometer is not used to measure thermal energy because it does not give information about the _____ energy of the particles in the substance.
