The wind-chill index is modeled by the function w = 13.12 + 0.6215t − 11.37v0.16 + 0.3965tv0.16 where t is the temperature (°c) and v is the wind speed (km/h). when t = 2°c and v = 32 km/h, by how much would you expect the apparent temperature w to drop if the actual temperature decreases by 1°c? (round your answers to two decimal places.)

The flame produced by the burner of a gas (propane) grill is a pale blue color when enough air mixes with the propane (c3h8) to burn it completely. for every gram of propane that flows through the burner, what volume of air is needed to burn it completely? assume that the temperature of the burner is 195.0°c, the pressure is 1.05 atm, and the mole fraction of o2 in air is 0.210.
