How does Energy Transfer effect Temperature?

When you turn on a radiator what will happen to the temperature of the room?

• It will stay the same

• It will increase

• It will decrease

Why does this happen to the temperature of the room when you turn the radiator on?

• The radiator takes thermal energy away from the room

• The radiator destroys the energy in the room

• The radiator creates energy so the room gets warm

• The radiator adds thermal energy to the room

Now you turn the radiator off and open a window. What will happen to the temperature of the room?

• It will stay the same

• It will increase

• It will decrease

Why does turning off the radiator and opening the window do this to the room? select all options that explain why

• Air with lots of thermal energy will leave through the window.

• The outside air destroys the thermal energy that was inside the room making it colder.

• The total thermal energy of the room will decrease.

• Air in the room will be replaced by air with less thermal energy from outside.

When an object loses thermal energy its temperature _________

When an object gains thermal energy its temperature _________

Thermal energy always moves from....

• Colder objects/areas to hotter objects/areas

• Hotter objects/areas to cooler objects/areas

Which direction is thermal energy being transferred? Ice cubes added to a fizzy drink

• Room --> Drink

• Drink --> Ice cubes

• Ice cubes --> Drink

• Drink --> Surroundings

How will the temperature of each object change? Ice cubes added to a fizzy drink

• drink will get warmer

• Ice cubes get colder

• Ice cubes will get warmer

• Drink will get colder

Which direction is thermal energy being transferred? Ice cube tray of water in the freezer

• Water --> Freezer

• Freezer--> water
