Q1A metal block X of mass 8 kg is heated by an electric heater. The electric heater is marked 240V, 160 W, 40*c rise in temp is obtained after the heater is used for 4 min. Neglect the heat lost , what is the specific heat capacity of metal X in SI unit?

Q2 How much heat is needed to change 600g of ice at 0*c to water at 60 *c ( specific latent heat of fusion of ice =3.34 x 10^5, specific heat capcity of water = 4200)

Q2 ans are u sure?

your working i think wrong..you no use mL??

use Q = mL is it?

how??? D:

is it m1L1=M2L2

I bodoh at this chapter, really.
