The formula for the quantity of heat Q = m s t
m- mass 0.375 kg s - specific heat capacity of water (4180 J/kg/K) t - the temperature change (25 deg C)
So, Q = 0.375 x 4180 x 25 = 39187.5 J
q(joules) = mass * specific heat * change in temperature
q = (5 grams H2O)(4.180 J/gC)(35o C - 25o C)
= 209 joules of heat

The SI unit of heat is the Joule. It can also be measured in a calorimeter, where one calorie is the amount of energy needed to raise one gram of water by one degree Celsius.
to solve this we use the formula Q(heat) = mc(change in temp) so, Q=(10g)(4.19J/gC)(18-22) Q=-167.6kJ of heat.
If you leave water alone, it is in liquid form. If you raise the temperature of water to boiling, it creates steam. Is this a gas? If you lower the temperature to freezing, it becomes a solid.
The amount of energy required to raise 1 kg of a substance by 1 degree Celsius is called the "Specific Heat Capacity," or just specific heat, of a substance. This is an intensive property of the particular substance.
mmmm enthalpy
The number of calories required will depend on the mass of water which is to be heated.
that means more energy is needed to raise the temperature of 1kg of liquid from 1 Celsius than water.
