P1V1 = P2V2 (740 torr)(500 ml) = (780 torr)V2 V2 = (740 torr)(500 ml) / (780 torr) V2 ~ 474 ml

Is helium a liqiud or a solid or gas?
Helium at standard temperature and pressure - is a gas.
Is helium a solid liquid or gas roomtemp?
Under standard conditions of pressure and temperature Helium is a gas.
Why hydrogen and helium does not satisfy joule Thomson effect?
As the gs flow from high pressure to low pressur using the porus plug the temperature of the gas increases as the pressure of the gas decreases. As we know in all this process the enthalpy is constant . So, to stay it constant the internal energy increases which lead to increase in temperature of the gas. Formula h=u+pv h--- enthalpy u-- internal energy p--pressure v---volume
What would increase the pressure inside a tank of helium gas?
You have several options, including:Increase the temperature of the gas, keeping the volume and mass of gas constant.Decrease the volume of the tank (e.g. with a piston), keeping the temperature and mass of gas constant.Add more gas to the tank, keeping the volume and temperature constant.
Will all the real gas be liquefied at high pressure?
No. It takes a combination of pressure and temperature to liquefy some gases. Hydrogen and helium were the last gases to be liquefied and that was with pressure and extremely low temperature.

Are hydrogen and helium gases?
They can be depending on the temperature and pressure. They can also be liquids and solids. At room temperature and pressure they are gases.
Is helium a solid liquid or gas roomtemp?
Under standard conditions of pressure and temperature Helium is a gas.
What is the inversion temperature of Helium at a pressure of 330 bars?
This is a stupid question

Why a helium weather balloon expands as it rises in the air. assume that the temperature remain constant.?
When the helium balloon starts gaining height, the pressure decreases and as the gas molecules are very freely movable (higher than the normal). They move apart from each other in the mean while they make the balloon to expand. The decrease in atmospheric pressure relative to pressure inside the balloon causes it to expand.

What gas is likely to behave as an ideal gas when subjected to high temperature and low pressure?
Helium
Helium is most likely to behave as an ideal gas when it is under?
low pressure and high temperature
Is helium solid or gas or liquid?
It is a gas.Answer:Helium can be in any state (solid,liquid or gas) depending on its pressure and temperature. At 2.5 MPa:Below -272.20oC it is a solidAbove -268.93oC it is a gasBetween these two temperatures it is a liquid
