How do you find the specific heat of a gas?
The specific heat at constant volume for a gas is given as (UT)V=cv ( U T ) V = c v . The specific heat at constant pressure for an ideal gas is given as (HT)V=cp=cv+R ( H T ) V = c p = c v + R .

Can specific heat of a gas be negative?
Yes it can be if you expand a gas at ultra high rate along with heating it up slowly then the gas will cool down, the rate of decrease in temperature will be higher than increase by heating so specific heat will be negative in that case. And heat is added in system therefore its always positive.
Why are gases not ideal?
At relatively low pressures, gas molecules have practically no attraction for one another because they are (on average) so far apart, and they behave almost like particles of an ideal gas. At higher pressures, however, the force of attraction is also no longer insignificant.
Is steam a perfect gas?
Steam behaves well as an ideal gas if not too close to the saturation line if you place yourself on a Mollier chart, when the temperature and enthalpy lines coincide and are straight, horizontal lines, then it behaves as ideal, and this you can easily see on the chart.
Is h2o ideal gas?
Note that H2O provides thermodynamic properties assuming ideal gas behavior. Use STEAM or WATER to provide real fluid properties in the subcooled, saturated mixture, and superheated regimes.
Is Vapour and gas same Why?
Vapor refers to a gas phase at a temperature where the same substance can also exist in the liquid or solid state, below the critical temperature of the substance. The term gas refers to a compressible fluid phase.
Is acetone a gas or vapor?
Acetone is a vapor, since it is normally a liquid at room temperature, which is the definition of a vapor.
