Suppose you start your day in denver, on a cool 10∘c spring day. the local atmospheric pressure is 85 kpa. you fill your car's tires until the gauge shows 210 kpa (about 30 psi). you then drive up to fairplay, colorado, where the atmospheric pressure is lower-- 70 kpa --and the temperature drops to 0∘c. when you finish lunch, you check your tire pressure.
a. what does the gauge read? and units.
show the math on how to solve this question.

If you touch a hot light bulb and get burned, that is an example of a. radiation b. convection c. conduction

What is the freezing point of radiator fluid that is 50% antifreeze by mass? kf for water is 1.86 ∘c/m.

Ahair dryer is basically a duct in which a few layers of electric resistors are placed. a small fan pulls the air in and forces it through the resistors where it is heated. air enters a 1200 w hair dryer at 100 kpa and 22°c and leaves at 47°c. the cross-sectional area of the hair dryer at the exit is 60 cm2. neglecting the power consumed by the fan and the heat losses through the walls of the hair dryer, determine (a) the volume flow rate of air at the inlet and (b) the velocity of the air at the exit.
