Josh did an experiment recording the changes in temperature in sand and water when exposed to a light source, and then when
the light source was removed. Josh noticed that the sand heated up faster than the water and then cools faster than the water.
Josh concludes that
-1)
A)
sand is the better insulator
B)
water is the better conductor
water is the better insulator.
D)
sand has a higher heat capacity
