Before the start of a trip, air in a tire is at 320 kPa gage pressure and 27°C temperature. At the end of the trip the tire pressure is 360 kPa gage. Atmospheric pressure is 100 kPa. What is the temperature of air in the tire at the end of the trip in °C ? (Assume the air volume in the tire is unchanged, no air leaks out, and the air has ideal gas properties)…

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
