A piston has an external pressure of 15.0 atm. How much work has been done in joules if the cylinder goes from a volume of 0.170 liters to 0.600 liters?
Express your answer with the appropriate units.
Alcohols are less volatile than ethers of the same molecular weight, but the two classes of compounds have approximately the same solubility in water because:
