SP1.  a) Is the modulus of elasticity of steel an extensive or intensive property? Explain why. b) Is the caloric content (i.e., number of calories) of a Big Al’s milkshake an extensive or intensive property? Explain why. SP2.  The temperature difference between a hot water pipe and the surrounding air is 32F. Express this difference in units of C, K, and R. SP3.  An air pressure gage indicates a tire pressure of 33 psig when the atmospheric pressure is 1 atm. Determine the absolute air pressure inside the tire in units of psi, kPa, inHg, and inH2O.
