A sample of gas at 15°C at 1 atm. has a volume of 2.58 dm³. When the temperature is raised to 38°C at 1 atm does the volume of the gas increase? If so, calculate the final volume.

A sample of gas has a volume of 8.5 dm³ at an unknown temperature. When the sample is submerged in ice water at 0 °C, its volume gets reduced to 6.37 dm³. What is its initial temperature ?

Of two samples of nitrogen gas, sample A contains 1.5 moles of nitrogen in a vessel of volume of 37.6 dm³ at 298K, and the sample B is in a vessel of volume 16.5 dm³ at 298K. Calculate the number of moles in sample B.

Hydrochloric acid is treated with a metal to produce hydrogen gas. Suppose a student carries out this reaction and collects a volume of 154.4 x 10^-3 dm³ of a gas at a pressure of 742 mm of Hg at a temperature of 298 K. What mass of hydrogen gas (in mg) did the student collect ?

It takes 192 sec for an unknown gas to diffuse through a porous wall and 84 sec for N₂ gas to effuse at the same temperature and pressure. What is the molar mass of the unknown gas ?

Give the graphical representation of Boyle's law.

How does the volume of a gas vary with temperature at constant pressure? Explain with the help of a plot between volume is temperature.

Explain the term 'Boyle's point.' Mention is significance.

Show how the molar volume of a real and ideal gas are related to each other?

Mention the application of Dalton's law.
