Mr. and Mrs. Brennick open several windows to cool off their home. After a few minutes, they close the windows. They measure the temperature, and it is 5°C cooler than it was before they opened the windows. Which statement below best explains why that happened?

• The outside air added cold to the air in the room.

• The air particles in the room transferred kinetic energy to the air particles from outside.

• The air particles mixed so now all the air particles have less kinetic energy.

• The outside air particles added kinetic energy to the air particles in the room

What is Convection?

• When heat is passed from particle to particle through an object.

• When particles get heated, expand, and become less dense.

• When heat transfers by waves through empty space.

Which statement describes the energy changes that occur when water in a tea kettle is heated on a stove that uses natural gas?

• Some of the chemical energy in the natural gas transforms into thermal energy, which heats the water. Then some of the thermal energy changes into sound energy when the water forms steam and the steam leaves the kettle.

• Some of the thermal energy in the natural gas transforms into sound energy when the water becomes hot. Then some of the sound energy changes into light energy when the kettle becomes warm.

• Some of the electrical energy in the natural gas transforms into thermal energy, which causes the water to form steam. Then some of the thermal energy changes into sound energy and light energy when the steam leaves the kettle.

• Some of the light energy in the natural gas transforms into chemical energy in the water. Then some of the chemical energy changes into kinetic energy when steam leaves the kettle and into sound energy when the water boils.
