how much energy is required to melt 1.5 kg of lead? (refer to table of latent heat values.)

a. 36.8 kj
b. 1307 kj
c. 16.3 kj
d. 17.1 kj

the temperature of the gas, in k, not celsius.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
