A closed tank contains pure nitrogen gas at a pressure of 855 mmHg and a temperature of 26.3 °C. What would the pressure be
if the tank were heated to 1253 °C? (pay attention to units)

If the tank were heated to 1253ºC, the pressure of the tank would be 40,734.41 mmHg.

Explanation:

Given that a closed tank contains pure nitrogen gas at a pressure of 855 mmHg and a temperature of 26.3ºC, to determine what the pressure would be if the tank were heated to 1253 ° C the following calculation must be performed:

26.3 = 855

1.253 = X

(1,253 x 855) / 26.3 = X

1,071,315 / 26.3 = X

40,734.41 = X

Therefore, if the tank were heated to 1253ºC, the pressure of the tank would be 40,734.41 mmHg.
