Question

1 mole of a gas occupies volume 1.00 x 10-2 m³ in a gas cylinder whose pressure is equal to 2.50 x 105 Pa.The temperature of cylinder is:

Options
  • A

    227K

  • B

    300K

  • C

    370K

  • D

    390K

Explanation

Using general gas equation aka ideal gas equation

PV=nRT

Plugging in the values, we get:

2.5x10⁵ x 1x10-²=1x8.3xT

Note: make sure that all the values are in SI units, and in physics particularly take R value that has SI units.

T= 300K

As per calculation, this option is incorrect.
