Answer: The temperature rise is
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed by ice = 5280 J
m = mass of ice = 2.40 kg = 2400 g (1kg=1000g)
c = heat capacity of water =
Initial temperature =
Final temperature =
Change in temperature ,
Putting in the values, we get:
Thus the temperature rise is
