The gases in a hair spray can are at a temperature of 24 °C and a pressure of 42 lbs/in 2. If the gases in the can reach a pressure of 100.0 lbs/in 2, the can will explode. To what
temperature in Kelvin must the gases be raised in order for the can to explode? Assume
constant volume.

Hot air balloons float in the air because of the difference in density between cold and hot air. in this problem, you will estimate the minimum temperature the gas inside the balloon needs to be, for it to take off. to do this, use the following variables and make these assumptions: the combined weight of the pilot basket together with that of the balloon fabric and other equipment is w. the volume of the hot air inside the balloon when it is inflated is v. the absolute temperature of the hot air at the bottom of the balloon is th (where th> tc). the absolute temperature of the cold air outside the balloon is tc and its density is ďc. the balloon is open at the bottom, so that the pressure inside and outside the balloon is the same. as always, treat air as an ideal gas. use g for the magnitude of the acceleration due to gravity.

Using data from seismic waves, geologists have learned that earth’s interior is made up of several
