Energy of a gas/litre is 600 joule, then what will be its pressure?

Options

  1. A4 10^5 N/m ^2
  2. B10^5 N/m ^2
  3. C6 10^5 N/m ^2
  4. D3 10^5 N/m ^2

Correct answer

A. 4 10^5 N/m ^2

Step-by-step solution

The translational kinetic energy of an ideal gas is given by E = 3 2 PV Rearranging for pressure, we get P = 2E 3V Given E = 600 J and V = 1 litre = 10⁻³ m ^3 Substituting the values: P = 2 600 3 10⁻³ P = 400 10^3 = 4 10^5 N/m ^2 Answer: 4 10^5 N/m ^2
