Question 18 :
Assertion: Helium will have fewer dispersion forces between its atoms than the other noble gases
Reason: As the mass of nonpolar atoms and molecules increases, dispersion forces increase

Question 30 :
When $2$ g of gas A is introduced into an evacuated flask kept at $25^oC$, the pressure was found to be $1$ atm. If $3$ g of another gas B is then added to the same flask containing A, the pressure becomes $1.5$ atm. Assuming ideal behaviour, the ratio of molecular weights $(M_A:M_B)$ is :
