on a winter day the temperature drops from -15c too -25C overnight. if a pan sitting outside contains 0.50 kg of ice, how much heat is removed from the ice for the temperature change?

Answer 1

-15 to -25 = 10 degree C change.
q removed = mass ice x specific heat ice x 10
mass ice = 500 g
specific heat ice = 2.108 J/g*C
