A cold metal spoon is placed in a bowl of hot soup. Which best describes how the spoon is affected?

• The heat from the soup does not affect the temperature of the spoon.

• The heat from the soup is conducted through the spoon, making the spoon warmer.

• The cold air in the room radiates into the soup, cooling it, and keeping the spoon cool.

• The cold from the spoon is conducted into the soup, causing the soup to cool to the same temperature as the spoon.T

Which best explains why a hot air balloon floats?

• The heated air expands to fill the balloon. The air in the balloon is now lighter than the surrounding air, causing the balloon to rise.

• The heated air expands to fill the balloon. The air in the balloon is now heavier than the surrounding air, causing the balloon to rise.

• The heated air contracts to fill the balloon. The air in the balloon is now denser than the surrounding air, causing the balloon to rise.

• The heated air contracts to fill the balloon. The air in the balloon is now lighter than the surrounding air, causing the balloon to rise.

Energy from the sun travels to the earth in the form of ​ (a)   . It warms the waters at the Equator, which then cause the warm waters to rise towards the poles, cool, sink, and return to the Equator. This forms a ​ (b)   current. Then when you step into the water, the heat is ​ (c)   to you.

Match these

• Conduction

• Heat transfers through waves/rays

• Convection

• Liquid (or air) heats up, speeds up and spreads out, becoming less dense. As it rises, it cools, slows, and comes back together. This increases density, making it sink again.

• Radiation

• Heat transfers from objects that are touching.
