Name or state the following :
- The law which states that pressure remaining constant the volume of a given mass of dry gas is directly proportional to it's absolute [Kelvin] temperature.
- The law which studies the relationship between pressure of a gas and the volume occupied by it at constant temperature.
- An equation used in chemical calculations which gives a simultaneous effect of changes of temperature and pressure on the volume of a given mass of dry gas.

It is required to reduce the volume of a gas by 20% by compressing it at a constant pressure. To do so, the gas has to be cooled. If the gas attains a final temperature of 157°C, find the initial temperature of the gas ?
At a given temperature the pressure of a gas reduces to 75% of it's initial value and the volume increases by 40% of it's initial value. Find this temperature if the initial temperature was -10°C.
Give reasons for the following :
Gases unlike solids and liquids exert pressure in all directions.
Give reasons for the following :
Gases have lower densities compared to solids or liquids.
