Question

3. If a gas has a pressure of 32.1 psi at a temperature of 25°C, then what is the new pressure if the temperature is increased to 75°C?

Answer 1

P2 = 37.5 psi

Step-by-step explanation:

P1 = 32.1 psi

T1 = 25°C + 273 = 298K

T2 = 75°C + 273 = 348K

P2 = ?

P1/T1 = P2/T2

or

P2 = (T2/T1)P1

= (348K/298K)(32.1 psi)

= 37.5 psi
