Question 1
An ideal gas expands against a constant external pressure of 2.0 atmospheres from 20 litre to 40 litre and absorbs 10 kJ of heat from surrounding. What is the change in internal energy(in J) of the system? (Given: 1 atm-litre =101.3J)
Question 2
2 mole of zinc is dissolved in HCl at 25°C. The work done in open vessel is:
Question 3
A sample of an ideal gas is expanded 1m3 to 3m3 in a reversible process for which P = KV2, with K = 6 bar/m6. Work done by the gas(in KJ) is :
Question 4
Heat absorbed by a system in going through a cyclic process shown in figure is :
Question 5
What is the final temperature of 0.10 mole monoatomic ideal gas that performs 75 cal of work adiabatically if the initial temperature is 227°C? (use R = 2 cal/K-mol)
