Question

A rigid nitrogen tank stored inside a laboratory has a pressure of 30 atm at 06:00 am when the temperature is 27°C. At 03:00 pm, when the temperature is 45°C, the pressure in the tank will be _______ atm. [nearest integer]

Answer 1

Since

P ∝ T

Hence,

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$

(p1 is pressure ar 6 am)

(p2 is pressure ar 3 pm)

$\frac{30}{300}=\frac{P_2}{318}$

P2 ≃32 atm
