Answer:
Explanation:
Firstly, we need the specific heat capacity of water which is typically around 4200J/kg (if the mass is in kg) or 4.2 J/g ( if mass is in g)
The formula for the heat energy needed is
E=mct
Where E is the heat energy, m is the mass of water, c is the specific heat capacity and t is the change in the temperature.
E= 6 x 4.2 x 15
= 378 J
