The gas in an aerosol container is at a pressure of 3.50 atm at 24.0C. The caution on the container warns against storing it at
AVprozaik [17]

Answer:

4.34atm

Explanation:

The following data were obtained from the question:

P1 = 3.50 atm

T1 = 24°C = 24 +273 = 297K

T2 = 95°C = 368K

P2 =?

Using P1 /T1 = P2 /T2, we can obtain the new pressure as follows:

P1 /T1 = P2 /T2

3.5 / 297 = P2 / 368

Cross multiply to express in linear form:

297 x P2 = 3.5 x 368

Divide both side by the 297

P2 = (3.5 x 368) /297

P2 = 4.34atm

Therefore, the gas pressure in the container at 95°C will be 4.34atm
