Cunoscându-se că la 25C presiunea oxigenului dintr-un recipient este de 4 atmosfere, să se afle la ce temperatură oxigenul din recipient va avea presiunea de 8 atmosfere

The container will have a pressure of 8 atm when the temperature is 50 degrees Celsius

Explanation:

To calculate this temperature, we need a gas law that relates temperature and pressure.

This is the Gay Lussac’s law and we know from it that temperature and pressure are directly related

Thus;

P1/T1 = P2/T2

From the question;

P1 = 4 atm

T1 = 25 degrees celsius

P2 = 8 atm

T2 = ?

Substituting these values, we have;

4/25 = 8/T2

4T2 = 8 * 25

4T2 = 200

T2 = 200/4

T2 = 50 degrees Celsius
