(a) the water density is 
, and 1 liter corresponds to a volume of 
. Therefore we can find the mass of the water in the first case:
The amount of heat supplied to the water to raise its temperature by
is
(1)
where
is the specific heat capacity of the water.
Using the data, we find
We want to find the increase in temperature if we transfer the same amount of heat Q to 2 liters of water. The mass of 2 liters of water is
And so by re-arranging equation (1) we can calculate the new increase of temperature:
(b) Now we have 3 liters of water. SImilarly to point (a), the mass is now
And so, the increase in temperature if we use the same amount of heat as before is
