Question

Hydrogen gas in a container of volume $20$ litre. Average translation kinetic energy of all its molecules is $1.5\times {10}^5$J. Pressure of hydrogen in cylinder is:

• A. $2\times {10}^{6}N/m^2$
• B. $3\times {10}^{6}N/m^2$
• C. $4\times {10}^{6}N/m^2$
• D. $5\times {10}^{6}N/m^2$

Answer 1

The correct option is D $5\times {10}^{6}N/m^2$

Given: Volume=$20Litre$

Average K.E=$1.5X{10}^{5}J$

Option D is correct answer.
