1 mole of H2 gas is contained in a box of volume V = 1.00 m3 at T = 300 K. The gas is heated to a temperature of T = 3000 K and the gas gets converted to a gas of hydrogen atoms. The final pressure would be

a) same as the pressure initially

b) 2 times the pressure initially

c) 10 times the pressure initially

d) 20 times the pressure initially

Answer:

The correct option is d) 20 times the pressure initially

Explanation: Because the container’s volume (V) remains constant. As a result, when the temperature (T) increases tenfold (from 300 K to 3000 K), pressure (P) increases tenfold, as P is proportional to T.
