The air inside an inflatable stand-up paddle board is 73.0F. A gauge measures the pressure of this air to be 11.0 psi. If someone naps on the board in the sun, so that the volume of the air inside is reduced by 11% and the temperature increases to 102F, what is the final gauge pressure of this air, in psi? Pressure unit conversion: 1.00 psi = 0.0680 atm (1.) 73.0 F = 295.9 K (2.) 102 F = 312.0 K (3.) gauge pressure 11.0 psi = absolute pressure 1.748 atm (4.) What is the final gauge pressure of the air inside the paddle board, in psi? Pfinal = 13.03 X psi
