How much energy is needed to change the temperature of 50.0 g of water by 15.0oc?

3135 J of energy is needed to change the temperature of 50g of water by .

Given :

Mass of water is 50g

Change in temperature =

Solution :

We know that energy needed to increase the temperature of a substance is,

  ---- (1)

where,

m is the mass of the substance,

is the specific heat capacity of the substance,

  ---   (specific heat of water)

and is the change in temperature.

Now put the values of  in equation (1) we get,

3135 J of energy is needed to change the temperature of 50g of water by .
