Answer 1

Answer #1

According to First law of thermodynamics, energy neither be created nor be destroyed. It can be transformed from one form to other form. If one form of energy disappears, equivalent form of other form of energy appears.

Mathematically it is expressed as

dQ = dU + dW

Where dQ is the amount of heat absorbed

dU is the change in internal energy.

dW is work done by the system on surroundings.

Given that

Amount of heat absorbed = 48.62 cal = 48.62*4.184 J

= 203.42 J

dW = 112.15 J

dU = dQ - dW

= 203.42 J - 112.15 J

= 91.28 J
