• Water has highest specific heat.

• ​Air has lowest specific heat.

• Thermal energy is absorbed faster between air and sand than between air and water.

• Sand releases thermal energy faster than water.

• Air above sand will release energy faster than air above water.

• Water has higher specific heat than sand.

• Water releases energy slowly.

• Air above water stays warmer for a longer time.
