Two vessels of the same size are at the same temperature. One of them holds on kg of `H_2` gas and another 1 kg of `N_2` gas.
Which of the vessels is under greater pressure and why?

Two vessels of the same size are at the same temperature. One of them holds on kg of H_2 gas and another 1 kg of N_2 gas. Which of the vessels contains more molecules?

Two vessels of the same size are at the same temperature. One of them holds on kg of H_2 gas and another 1 kg of N_2 gas. In which vessel is the average molecular speed greater? How many times greater?

In two vessels of 1 litre each at athe same temperature 1g of H_(2) and 1g of CH_(4) are taken. For these gases:

The closed containers of the same capacity and at the same temperature are filled with 44 g of H_(2) in one and 44 g of CO_(2) in the other . If the pressure of carbon dioxide in the second container is 1 atm , then pressure of hydrogen in the first container would be :

The mass of a body as measured by two students is given as 1.2 kg and 1.23 kg. Which of the two is more accurate and why?

Two spherical bobs, one metallic and the other of glass, of the same size are allowed to fall freely from the same height above the ground. Which of the two would reach earlier and why?

The volume of vessel A is thrice the volume of another vessel of another vessel B and both of them are filled with the same gas. If the gas in vessel A is at thrice the temperature and thrice the pressure as compared to that of gas in vessel B. what is ratio of gas molecules in the two vessels?

Two closed vessels of equal volume containing air at pressure P_(1) and temperature T_(1) are connected to each other through a narrow tube. If the temperature in one of the vessels is now maintained at T_(1) and that in the other at T_(2) , what will be the pressure in the vessels?

A vessel is filled with a gas at a pressure of 76 cm of mercury at a certain temperature. The mass of the gas is increased by 50% by introducing more gas in the vessel at the same temperature. Find out the resultant pressure of the gas.

A vessel is filled with an ideal gas at a pressure of 20 atm is at a temperature of 27^@ C . One half of the mass is removed from the vessel and the temperature of the remianing gas is increated to 87^@C . What will be the pressure at this temperature?
