The Tacoma Narrows Bridge is 1822m long and is constructed of steel. How much longer is the bridge on a warm summer day (99∘F) than on a cold winter day (2∘F)?
(NOTE: Careful of your units!)
Early in the morning, when the temperature is 4∘C, gasoline is pumped into a car’s 40L steel gas tank until the tank is filled to the top. Later in the day the temperature rises to 30∘C. Since the volume of gasoline increases more for a given temperature increase than the volume of the steel tank, gasoline will spill out of the tank. How much gasoline spills out in this case?
Use β=0.000950K−1 for gasoline.
Enter your answer in liters [L].
A gas has a temperature of 625K and a pressure of 1200kPa. Find the volume occupied by 8.2mol of this gas, assuming it is ideal.
Enter your units in m3. [m^3]
A cylindrical flask is fitted with an airtight piston that is free to slide up and down. A mass rests on top of the piston. The initial temperature of the system is 486K and the pressure of the gas is held constant at 19kPa. The temperature is now increased until the height of the piston rises from 23.4cm to 35.6cm. What is the final temperature of the gas?
During a windstorm a 40.3 ms wind blows across the flat roof of a small home. Find the difference in pressure between the air inside the home and the air just above the roof, assuming the doors and windows of the house are closed. The density of air is 1.29kgm3.
Be sure to enter the correct S.I. units.
The heights of the air just below the roof and just above the roof are essentially equal.
The air inside the house is not moving.
