Helium pressure question plz help?
A vessel containing 39.5 cm3 of helium gas at 25 degrees C and 106kPa was inverted and placed in cold ethanol. As the gas contracted, ethanol was forced into the vessel to maintain the same pressure of helium. If this required 7.7cm3 of ethanol, what was the final temperature of the helium?
