Question 7 :
Work done in converting 1 g of ice at $- 10^o$C into steam at $100^o$C is

Question 9 :
If the heat of $110 j$ is added to a gaseous and change in internal energy is $40 J$, the amount of external work done is:

Question 10 :
Assertion: First law of thermodynamics can be applied for ideal gases only. Reason: First law is simply, law of conservation of energy.

Question 11 :
A thermally insulated rigid container contains an ideal gas. It is heated through a resistance coil of 100$\Omega $ by passing a current of 1 A for five minutes, then change in internal energy of the gas is<br/>

Question 13 :
In a thermodynamic process pressure of a fixed mass of a gas is changed in such a manner that the gas releases $20J$ of heat and $8J$ of work is done on the gas. If initial internal energy of the gas was $30J$, what will be the fixed internal energy?
