Radiation
Conduction
Convection
Insulation
A student conducts an experiment to compare how well different materials transfer heat. He places ice cubes of equal size in four different containers. Then he measures how long it takes for each ice cube to melt completely. The results are shown to the left. Which material is the best insulator of heat?
Drinking glass
Metal can
Foam cup
Plastic cup
If you have two pieces of metal (see illustration) in a very well insulated container, what temperature will both pieces of metal equal to if given enough time?
90
50
45
A scientist places balls of wax at the ends of four rods made of different materials. She then places the rods, with the waxed ends up, in a beaker of hot water and measures how long it takes for the wax to melt completely on each rod. Her results are in the table. Which is the best conclusion?
Stainless steel is the best insulator
Copper is the best conductor
Glass insulates better than wood
Stainless steel insulates better than glass
