Sentences with phrase «heat at constant volume»

where is the specific heat at constant volume, is the number of moles of the gas, is the gas constant, and is the temperature.

Finally, heat content of the CO2 will be higher because of the higher specific heat at constant volume because there are 3 modes of vibrational motion rather than one (N2).

Not exact matches

For example any (constant) volume of ideal gas at room temperature (20 °C) increases its pressure by a factor fo 4.3 when heated to 1000 °C.

Btu per cubic foot: The total heating value, expressed in Btu, produced by the combustion, at constant pressure, of the amount of the gas that would occupy a volume of 1 cubic foot at a temperature of 60 degrees F if saturated with water vapor and under a pressure equivalent to that of 30 inches of mercury at 32 degrees F and under standard gravitational force (980.665 cm.

The gas at the top of the tube would be warmed (thus increasing its pressure slightly (ideal gas laws temperature change constant volume tube) and like a piston this pressure increase would propagate down the tube at the local speed of sound in the gas causing adiabatic heating of the gas in each subsequent layer until it reached the bottom of the tube, instantly replacing the heat lost to the silver wire.

That way you might be able to understand how the heat capacity at constant volume is related to the number of degrees of freedom available to store heat at the molecular level (instead of stating that it doesn't depend on them, which is simply incorrect).

But in any case the difference between constant pressure and constant volume is only a factor of 7/5 in the case of air, whereas latent heat increases PV about five times as fast as vapor loss contracts it at any realistic temperature.

captaindallas, not sure if you understood what I said, but basically if you heat air by 1 %, its volume increases by 1 % at constant pressure redcuing the density.

Cp is the heat capacity at constant pressure, Cv is the heat capacity at constant volume.
