2. A can of hair spray contains a polymer blend that gives support to hair and a volatile hydrocarbon propellant. A DOT-2P aerosol can is regulated to have a burst strength of 240 psi (or about 16.33 atm) which can be done with a remarkable minimum wall thickness of 0.007 in. using polymer laminated steel. A can of hair spray is loaded to 50 psi (or approximately 3.40 atm) at ambient temperatures (assume 74.0 degrees F for this problem). Assuming an ideal gas, if left in the backseat of a car on a hot day where the temperature reaches 139.0 degrees F. . .
c) At what minimum temperature (in degrees F) would the can burst?
