Question

The thermal capacity of 40g of aluminium (specific heat = 0.2 cal°g^-1 C^-1) is ___________

(a) 40cal°C^-1

(b) 160 cal°C^-1

(c) 200 cal°C^-1

(d) 8 cal°C^-1

I got this question in my homework.

I'm obligated to ask this question of Latent Heat topic in chapter Kinetic Theory of Gases of Engineering Physics I

Answer 1

Right choice is (d) 8 cal°C^-1

For explanation: Thermal capacity = mc

Thermal capacity = 40g×0.2cal g^-1 C^-1

                             = 80 cal°C^-1.
