If the gas pressure in an aerosol can is 148.5 kPa at 23.0°C, what is the pressure inside the can if it is heated to 298°C?

Answer 1

the equation needed in this context is: P2 / T2 = P1 / T1 where T must be in kelvin. therefore, P2 = P1 * T2 / T1. P1 = 148.5 kPa, T1 = 23.0 + 273.15 = 296.1₅ K and T2 = 298 + 273.15 = 571.₁₅ K. substituting in the above equation for P2, one gets P2 = 286 kPa. when the temp increases, the press should also increase. the result is consistent with this expectation
