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?
1. The volume of a gas with a pressure of 1.2 atm increases from 1.0 L to 4.0 L. What is the final pressure of the gas, assuming constant temperature?2. The gas with an initial volume of 24.0 L at a pressure of 565 mmHg is compressed until the volume is 16.0 L. What is the final pressure of the gas, assuming the temperature does not change?
You have a tank of compressed helium that has a volume of 12 L and a pressure of 12 atm. You filled party balloons that hold 3 liters each, here in San Francisco. How many party balloons could be filled? The temperature and n are constant. Remember the tank holds 12 L of helium even at atmospheric pressure.
The gas with an initial volume of 24.0 L at a pressure of 565 mmHg is compressed until the volume is 16.0 L. What is the final pressure of the gas, assuming the temperature does not change? A) 377 mmHg B) 760 mmHg C) 848 mmHg D) 500. mmHg E) 465 mmHg
Two moles of helium are initially at a temperature of 24.0 ∘C and occupy a volume of 2.50×10−2 m3 . The helium first expands at constant pressure until its volume has doubled. Then it expands adiabatically until the temperature returns to its initial value. Assume that the helium can be treated as an ideal gas. Part A What is the total heat supplied to the helium in the process? Part B What is the total change in internal energy of...
20. A compressed gas cylinder containing 24.0 g methane has a volume of 3.30 L. What pressure is the methane exert in the cylinder if its temperature is 25°C? 0.0900 atm 1.70 atm 1.11 atm 0.933 atm 11.1 atm
A 1.75 L volume of helium gas stored at 0.873 atm will have a temperature of 46.9oC. If the helium is compressed down to a volume of 523 mL while allowing the pressure to settle at 1,662 mmHg, what will the temperature of the helium gas now be, in oC? Give your answer to one decimal place, and in units of oC. Data: 1 atm = 760 mmHg, 0oC = 273 K, PV = nRT, R = 0.0821 L.atm.mol-1.K-1.
If 60.0 L of oxygen at 13.0°C and an absolute pressure of 2.45 atm are compressed to 53.8 L and at the same time the temperature is raised to 50°C, what will the new pressure be?
Suppose 14.3 moles of helium gas are confined at 57.3 oC in a volume of 31.0 L. Calculate the pressure (in bar) using the ideal gas law. .......................... bar
A helium balloon has a volume of 3.22 L at 21.4C and a pressure of 755mm Hg. a.) If the balloon is immersed in a cold temperature bath of -63.7C and the pressure remains constant, what will be the new volume in liters of the balloon? b.) If the same balloon is placed in a vacuum chamber and the pressure is reduced to .551 atm, what will the new volume of the balloon in liters, assuming the temperature remains constant?
