Helium in a cylinder with a piston and initially at 23 ∘C expands at constant atmospheric pressure. Part A What is the work that the piston does on the gas if the air expands from 0.030 m3 to 0.041 m3 ? Express your answer to two significant figures and include the appropriate units. Part B How many moles of gas are in the container? Express your answer using two significant figures. Part C Suppose that the work leads to a...
1) A cylinder is filled with 0.10 mol of an ideal gas at standard temperature and pressure, and a 1.4-kg piston seals the gas in the cylinder (see figure) with a frictionless seal. The trapped column of gas is 2.1-m high. The piston and cylinder are surrounded by air, also at standard temperature and pressure. The piston is released from rest and starts to fall. The motion of the piston ceases after the oscillations stop with the piston and the...
A cylinder of volume 43.8 L helium is filled to a gauge pressure of 1.72 x 10^7 Pa in a cylinder. a) With that amount of helium, how many balloons can be inflated to a volume of 4.0 L and pressure of 1.01 x 10^5 Pa, assuming that the balloons and the cylinder are at the same temperature? b) If the temperature of the balloons is 77 degrees Fahrenheit, then how many moles of helium are in one balloon? c)...
