An aerosol can contains gases under a pressure

Question

of 4.6 atm at 18◦C. If the can is left on a hot sandy beach, the pressure of the gases increases to 4.69 atm. What is the Celsius temperature on the beach

Answer 1

since PV/T is constant, if P increases by a factor of 4.69/4.6, T decreases by a factor of 4.6/4.69. T is Kelvin, of course.
