Find the temperature and the pressure of a gas inside the cylinder.
1. A gas at 71°C occupies a volume of 0.67 L. At what Celsius temperature will the volume increase to 1.70 L?
2. If it takes 0.0610 L of oxygen gas kept in a cylinder under pressure to fill an evacuated 2.72 L reaction vessel in which the pressure is 0.980 atm, what was the initial pressure of the gas in the cylinder?
In dry atmospheric air, the four most abundant components are N2, X = 0.808; O2, X = 0.1915; Ar, X = 9.34x10-5; and CO2, X = 4.066x10-4. Calculate the partial pressure of Ar, in torr, under standard atmospheric conditions.
How does an increase in pressure effect the solubility of a gas in a liquid? A. As pressure increases, gas solubility increases. B. As pressure increases, gas solubility remains the same. C. As pressure increases, gas solubility decreases.
A 33.0-g sample of an alloy at 93.0°C is placed into 258 g of water at 22.0°C in an insulated coffee cup. Assume that no heat is absorbed by the cup. If the final temperature of the system is 31.1°C
