The molecules of gas in this tank move around quickly because of:
Strong force of attraction
Gravity
Weak force of attraction
Large space in tank
Gas molecules inside a closed volume are constantly moving freely.
A gas is to be filled from a tank of capacity 10,000 litres into cylinders each having capacity of 10 litres. The condition of the gas in the tank is as follwos: (a) Pressure inside the tank is 800 mm of Hg. (b) temperature inside the tank is - 3∘C. When the cylinder is filled, the pressure gauge reads 400 mm of Hg and the temperature is 270 K. Find the number of cylinders required to fill the gas.
