How much heat do you need to raise the temperature of 150 g of ice from −30 °c to −15 °c ?

Answer : The amount of heat needed is, 9405 J

Explanation :

Formula used :

or,

where,

Q = heat required = ?

m = mass of ice = 150 g

c = specific heat of water =

= initial temperature  =

= final temperature  =

Now put all the given value in the above formula, we get:

Therefore, the amount of heat needed is, 9405 J
