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 pres
sure 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)…
With a vector, however, the sign simply tells you about the direction of the vector. If you're travelling with a velocity of 20 km/hr east, it means you're travelling east, and your speed is 20 km/hr.
