A monatomic ideal gas containing 7.95 moles at a temperature of 235 K are expanded isothermally from a volume of 1.23 L to a volume of 4.44 L.
a) Sketch a P vs.V graph.
b) Calculate the work done by the gas.
c) Calculate the heat flow into or out of the gas.
d) If the number of moles is doubled, by what factors do your answers to parts (b) and (c) change? Explain.
