I WILL GIVE BRANLIEST FOR ANSWER
Kristen goes to the beach with her family on a summer afternoon. Her parents set up a
beach umbrella as a protection from the bright sunlight, and they place a small folding
table under it. Kristen takes a can of lemonade from an ice chest and drinks half of it. Then
she places the can on the table and walks down to the water. The dry sand feels very hot to
her feet, but the wet sand at the water’s edge, being constantly lapped by tiny waves, feels
cool. After about an hour of walking along the beach, Kristen returns to the umbrella. She
picks up her can of lemonade, and it is now warm.
1. Why does the dry sand feel hot to Kristen’s feet?

2. Why does the wet sand feel cool to Kristen’s feet?

3. Why has Kristen’s can of lemonade become warm?

4. What example of thermal equilibrium can you identify in this scenario?
