Agas container is initially at 47 mm hg and 77 k (liquid nitrogen temperature.) what will the pressure be when the container warms up to room temperature of 25 c?

181.90 mmHg

In this case, we are given;

Initial temperature, T1 = 77 K

Initial pressure, P1 = 47 mmHg

Final temperature, T2 = 25 °C + 273

                                     = 298 K

We are required to find the final pressure;

Using pressure law;

P2 = (P1/T1)T2

    = (47/77K) × 298 K

    = 181.90 mmHg

Therefore, the new pressure will be 181.90 mmHg
