1) Helium gas with a volume of 2.60 litres, under a pressure of 0.180 atmospheres at a temperature of 314 K, is warmed until both the pressure and the volume are doubled. Consider Helium as a (monoatomic) ideal gas. The molar mass of Helium is 4.00g/ mol. (a) What is the final temperature? (b) What is the mass of the gas in the container? (c) How many atoms of Helium are present in this sample?
At constant temperature, a sample of helium at 3.46 atm in a closed container was compressed from 11.00 L to 4.00 L. What was the new pressure exerted by the helium on its container?
Q1. An isolated container is filled with 2.00 mole of helium gas at temperature 20 °C. a) How much heat must be transferred to the gas to increase its temperature to 200 °C if it is heated at constant volume? b) How much heat must be transferred to the gas to increase its temperature to 200 °C if it is heated at constant pressure? c) What is the work done in both process? Q1. An isolated container is filled with...
Which of the following is NOT true about helium gas and argon gas samples at the same temperature and pressure? Question 1 options: If you have twice as many moles of argon as helium, the volume of argon will be twice as large. The same number of moles of each will occupy the same volume. One mole each of helium and argon in a container will take up twice the volume of 1 mole of helium by itself. The same...
A 4.65 L sample of helium gas contains 0.900 g of helium. How many additional grams of helium gas must be added to the sample to obtain a volume of 6.48 L? Assume constant temperature and pressure. (MM He = 4.00 g/mol)
