I left some water sitting in the sun for 3 hours. If I put a thermometer in it, and had you guess the temperature, what question would you want to ask before guessing the correct temperature of my water?

40^o F      or        75^o F

Did you have ice in the water?

Insulator

Because it kept the soup warm. the temperature only dropped by 2 degrees.

Heat

I put my hot soup in two different cups. It started at 40⁰ Celsius.  The soup in cup A was 32^o degrees Celsius after 30 minutes. The soup in cup B was 38^o Celsius after 30 minutes.  I now know that the material used to make cup A was NOT a good______.  (Answer Why for extra points.)

Insulator

Because if it had been a good insulator the temperature of the soup would not have dropped so much. (From 40^o-32^o)
