hi i don’t understand this it’s percents of a number and it can’t have a percentage sign ty for solving it

The Quantity of heat require is

Step-by-step explanation:

This problem bothers on the topic of heat capacity.

Given data

mass of water m=  

converting from grams to kg we have =

initial temperature T1= 4°C

final temperature T2= 25°C

heat capacity of water =

The expression for the quantity of heat required is given has

substituting our given data we have

In kilograms we have to divide by
