Heat Test

A scientist is designing a new type of insulation for hot water pipes. Insulating hot water pipes helps save energy by:

• keeping heat from moving out of the water

• helping heat move into the water

• helping heat move out of the water

Bryan wants to know whether a wool sock or a cotton sock will be a better insulator. Bryan puts a wool sock around cup 1 and a cotton sock around cup 2. He fills both cups with hot water. How can he tell which sock is a better insulator?

• measure which cup of water stays hot the longest

• measure the temperature of each sock by itself

• measure how long it takes to drink the water

What happens when Kayla sticks a metal spoon that is at room temperature into a cup of boiling water?

• heat energy for the water will flow to the metal spoon, causing the spoon to increase in temperature

• heat energy from the metal spoon will flow into the water, causing the spoon to decrease in temperature

• the metal spoon will soak up the boiling water, causing the spoon to increase in temperature
