Specific Heat of Gases Enthalpy For an ideal gas the enthalpy - h - is a function of temperature. Change of enthalpy can be expressed as dh = cp dT (2) where dh = change in enthalpy (kJ/kg) cp= specific heat for gas in a constant pressure process (kJ/kgK Specific heat cp can ...
The heat capacity of a gas depends strongly upon the conditions under which heating is done, whether at constant pressure or at constant volume. Indeed, it was pointed out in Chapter 1 that the ratio C p / C υ is as high as 1.67 for a monatomic gas. It is possible to measure ...
This definition of specific heat is useful for solids and liquids, but is incomplete in case of gases. For example, if a gas is suddenly compressed, its temperature rises, even when no heat is exchanged with the surroundings. Here, H = 0, but t ≠ 0. So, s = \(\frac{H}{t}\) ...
SPECIFIC HEATS OF GASESNOTE: There are several questions that you will need to answer and write up inyour laboratory notebook before you start this experiment—see below.1 INTRODUCTIONThe specif i c heat of a substance is def i ned by:c =1NdQdT(1)where dQ is the amount of heat that ...
It was shown that when a gas flows through the tube, the resulting deflection of the galvanometer is an accurate measure of the heat capacity of the gas. Although this method has already been used with success up to temperatures of 500掳 C. by placing a calorimeter of this type in a ...
PROF. PARTINGTON'S book is remarkable in that, instead of dealing generally with the properties of gases, it selects for fuller treatment the single property of specific heat. In the case of steam, tables of fundamental data are available, in which the numerical results have been subjected to...

Ideal Gases An adiabatic process [8] means that no heat or matter is transferred to the surroundings therefore energy is only work done therefore entropy remains constant. (Poisson's equation: P V γ = constant) Ideal gas law: P V = mRT (2) Where P = pressure (...
