Statement-1: A gas from a flask is allowed to effuse through a pinhole, rate of effuison decreases lineary with time.
Statement-2: With time, gas pressure in flask decreases.

Statement-I : A gas effuses our from a flask through an orifice (pinhole), rate of effusion decreases linearly with time Because Statement -2 : Pressure of the gas in the flask decreases with passage of time

Statement -1 : When temperature is incrteased, viscosity of the gas decreases. Statement -2 : With the increase in temperature, the gas becomes lighter.

Write True or False for the following statement: With the decrease in the volume of a gas its pressure increases.______________.

A flask contains three times as many moles of H2 gas as it does O2 gas. If hydrogen and oxygen are the only gases present, what is the total pressure in the flask if the partial pressure due to oxygen is P?

The vapour of a substance effuses through a small hole at the rate 1.3 times faster than SO_(2) gas at 1 atm pressure and 500 K. The molecular weight of the gas is
