If 3.882 liters of helium its orwssure halved and its absolute temperathre halved , what will...
one mole of helium gas is spreading from initial volume of 2.0 liters to a final volume of 7.5 liter at 25C. a. find the work done against i) vacuum ii) external pressure of 2.0 atm b. what will be the value of dH? show calculations.
A weather balloon with a volume of 44L is filled with 2.0 mol of helium. What is the final volume, in liters if 3.0 mol of helium are added, to give a total of 5.0 mol of helium, if the pressure and temperature do not change?
Fun with a helium balloon A loosely filled balloon contains 4.5 liters of helium gas at atmospheric pressure (PA = 101 kPa) and room temperature T = 20 C. The gas in the balloon is then heated to body temperature, 37 C, by a student. (a) The pressure inside the balloon changes very little during the heating process. What is the change in the volume of the balloon? (b) How much work does the expanding balloon do on its environment?...
A balloon filled with helium gas at 1.00 atm occupies 9.3 L. What volume in liters will the balloon occupy in the upper atmosphere, at a pressure of 0.46 atm?
Imagine some helium in a cylinder with an initial volume of 1 liter and an initial pressure of 1 atm. Somehow the helium is made to expand to a final volume of 3 liters, in such a wat that its pressure rises in direct proportion to its volume. Sketch a graph of pressure vs. volume for this process Calculate the work done on the gas during this process, assuming there are no “other” types of work being done. Calculate the...
q15-A balloon is partly inflated with 5.05 liters of helium at sea level where the atmospheric pressure is 1.00×103 mbar. The balloon ascends to an altitude of 3.00 × 103 meters, where the pressure is 855 mbar. What is the volume of the helium in the balloon at the higher altitude? Assume that the temperature of the gas in the balloon does not change in the ascent.
A party balloon contains with a volume of 29.8 liters of air contains 1 moles of helium. If some gas escapes and 0.5 moles are still left inside the balloon, what volume in liters will the balloon have? Round your answer to the nearest tenth.
A mixture of nitrogen (N2) and helium has a volume of 250mL at 30 degree C and a total pressure of 745mmHg. (8.5, 8.6, 8.7) a. If the partial pressure of helium is 32mmHg, what is the partial pressure of the nitrogen? b. What is the final volume in liters, of the nitrogen at STP?
(2): A sample of helium at a pressure of 740. torr and in a volume of 2.58 L was heated from 24.0 to 750 °c. The volume of the container expanded to 2.81 L. What was the final pressure (in torr) of the helium? (3): What volume in liters does 0.136 g of O2 occupy at 20.0 °C and 2.36 atm? (4): A gas sample weighing 1.67 g has a volume of 276 mL at 589 torr and 28 °C....
a gas has a volume of 10 liters at 0 degrees celsius. what is the final temperature of the gas if its volume increases to 25 liters?
