(d) There are two samples of A and B. After 6000 joules of heat are added to each sample of A and B, which are both initially at 15°C, the final temperatures are 80°C for A, and 60°C for B. After the experiment, a student concludes that B must have a larger specific heat capacity since the temperature rise is smaller for the same amount of heat added. Comment and explain whether the student is correct.

please help me to solve part d, thanks a lot

(a) Find the amount of energy required to heat up 120 g of water at 12 °C to 80 °C. The specific heat
capacity of water is 4200 J kg-¹ °C.
(b) Find the amount of energy required to heat up 115 g of ice at 0 °C to steam at 100 °C. The specific
heat capacity of water is 4200 J kg-¹ °C. The specific latent heat of fusion of ice is 3.34 × 10³ J kg.
The specific latent heat of vaporization of water is 2.26 × 10° J kg-¹.
(c) Melting ice of mass 90 g is added to 650 g of liquid A at 32 °C. Find the final temperature of the
mixture, assuming that no energy is lost to the surroundings. The latent heat of fusion of solid A is 4130
J kg¹. The specific heat capacity of liquid A is 4800 J kg C. The specific heat capacity of water is
4200 J kg¹¹ C¹¹. The specific latent heat of fusion of ice is 3.34 x 10 J kg. The melting point of A is
-22.8 °C.
(d) There are two samples of A and B. After 6000 joules of heat are added to each sample of A and B.
