An aluminium block of mass 2.5 kg is supplied with 9000 J of thermal energy. This causes its temperature to rise by 4 K. Which expression gives the specific heat capacity of this aluminium, from this data?
[Assume that the block remains solid throughout, and that no additional energy is exchanged between the block and the surroundings.]

A. 9000 x 2.5 x 4 K kg^-1 K^-1

B. [(2.5 x 4)/9000] K kg^-1 K^-1

C. [(9000 x 2.5)/4] J kg^-1 K ^-1

D. [(9000)/(2.5 x 4)] J kg^-1 K ^-1

E. [(9000 x 4)/2.5] J kg^-1 K ^-1

[see below for original question format]

For this question, you should know the concept of Specific Heat Capacity(c).

It is the amount of heat required to raise the temperature of 1 kilogram of a substance by 1 kelvin.

It is given by- Delta(Q)= mc Delta(T)

where, Q= change in heat energy

m= mass

c= specific heat capacity

T= change in temperature

Put the given values in above formula to get value of c.
