Question

A cylinder of capacity 20 litres is filled with H2 gas the total average kinetic energy of translatory motion of its molecules is 1.5×10raise to 5J the pressure of hydrogen in the cylinder is?

Answer 1

The pressure of hydrogen in the cylinder is 5×10^6 N/m^2.

Explanation:

Given data:

Kinetic energy E = 1.5×10^5 J

Volume "V" = 20 L= 20×10^−3 m^3

Solution:

Pressure  = 2 / 3 E / V

               = 2 / 3 (1.5×10^5 / 20×10^−3)

               = 5×10^6 N/m^2

Hence the pressure of hydrogen in the cylinder is 5×10^6 N/m^2.
