fourresponsesbelow:
I.
II.
III.
IV.
Jennifer said that the temperature of the sand and water would increase by the
same amount since both are receiving the same amount of heat.
Afroja said that the water would get hotter than the sand because the water
molecules are free to move and transfer heat through convection.
Ashley said that the sand would stay the same temperature but the water would
get much hotter as it will absorb all the heat.
Ilene said that the sand will heat up and get much hotter than the water if the same
amount of heat is applied to both.
