Give reasons for the following:
Volumes of gases are converted to - standard temperature & pressure [s.t.p.] & then compared.

the values of standard temperature and pressure is :

The volume of 1 mol of a gas at standard temperature and pressure is .

Give reasons for the following: Gases exert pressure in all directions

Which of the following gases will have least volume if 10g of each gas is taken at same temperature and pressure?

Copy the following table which gives the volumes of gases collected under the same conditions of temperature and pressure and the number of molecules (X) in 20 litres of nitrogen. You are to complete the table giving the number of molecules in the other gases in terms of X.

Give reasons Need of mentioning temperature and pressure while stating its volume

Equal volumes of all gases under similar conditions of temperature and pressure contain equal number of atoms.

Equal volumes of all gases under the same conditions of temperature and pressure contain equal number of

Molar volume is the volume occupied by 1 mol of any ( ideal ) gas at standard temperature and pressure ( STP : 1 atmospheric pressure, 0^(@)C ). Show that it is 22.4 litres.

Two adiabatic containers have volumes V_(1) and V_(2) respectively. The first container has monoatomic gas at pressure p_(1) and temperature T_(1) . The second container has another monoatomic gas at pressure p_(2) and temperature T_(2) . When the two containers are connected by a narrow tube, the final temperature and pressure of the gases in the containers are P and T respectively. Then
