The Heat Transfer

What is heat energy?

• A form of energy that enables something to move

• A form of energy that gravitational

• A form of energy that flows from the hot object to the cold object.

• A form of energy that is stored in our food.

What is the unit that measures the amount of heat energy of an object?

• Joule

• Kelvin

• Fahrenheit

• Celcius

What is the device that is used to measure the amount of heat energy of an object?

• barometer

• anemometer

• thermometer

• calorimeter

What is not the unit for measuring heat energy?

• Newton Meter

• British Thermal Unit

• Kilometer per hour

• Joule

What is not the type of heat transfer?

• Boil the water on the stove

• The radio waves transmission

• The transfer of infrared waves from the sun to the earth's surface.

• The room that is cooled by the Air Conditioner

Which activity shows the heat is transferred through conduction?

• the sea breeze that blows in the morning.

• the sun that dries the seawater to leave salt particles.

• the ice is melted in our palms.

• the hot air balloon flies to the sky.

The heat energy flows from the hot object to the cold object, until two of the objects obtain the same temperature. This condition is known as... principle.

• Thermal Thermometer

• Thermal Equivalence

• Thermal Equilibrium

• Thermal Condition

What is temperature?

• The heat transfer by direct contact.

• The radiation of sun rays to the earth.

• The form of energy that flows from hot objects to cold objects.

• The measure of how hot or cold an object is.

What is conduction?

• A heat transfer occurs on gases and liquids by forming currents.

• A heat transfer because two objects have direct contact.

• A heat transfer from one object to another object in the electromagnetic wave that goes through a vacuum place.

• A heat transfer from the hotter objects to the colder objects.

Choose the event that shows conduction heat transfer

• The boiling water

• Touching the mug that contains hot coffee

• The air balloon rises up to the sky

• The occurrence of sea breeze and land breeze
