Tina is boiling water in a metal pot for a weather experiment. What is most likely the reason she would need to use a pot holder for moving the metal pot?

• radiation causes the pot to be hot.

• Conduction causes the pot to be hot.

• Convection causes the pot to be hot.

• Transpiration causes the pot to be hot.

which of the following is an example of radiation?

• Macaroni moving around in a pot of boiling water.

• steam rising form a boiling pot of grits being cooked.

• The sun shining through a window and warming a table.

• Bacon frying in a pan.

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.
