The specific heat of a gas is a measure of the amount of energy necessary to raise the temperature of the gas by a single degree. Since the amount depends on the process used to raise the temperature, there is a specific heat (cv) coefficient for a constant volume process, and a different valued coefficient for a constant pressure process (cp).Air takes up space. Air has mass/weight. Air is affected by heat. Air exerts pressure. Air can be compressed. Air is affected by altitude. Air Takes Up Space.

Properties of air For ideal gases, the properties cρ, k, µ, and Pr are independent of pressure. The properties ρ, ν, and α at a pressure P (in atm) other than 1 atm are determined by multiplying the values of ρ at the given temperature by P and by dividing v and α by P.• Specific Heat Capacities of an Ideal Gas--- 37 • The Adiabatic Process of an Ideal Gas--- 39 Ideal Gas Tables • Properties of Various Ideal Gases (at 300 K)--- 40 • Specific Heat Capacities of Air--- 41 • Critical Point Data of Various Substances--- 42 • Lee-Kesler Compressibility Chart--- 43 Air/Water Vapor Mixtures

Apr 01, 2015 · Specific heat means the heat to raise the temperature of 1 gram of the material by 1 degree C. So if you want to raise the temperature of that one gram from 19 to 35 degrees, that same gram will need 35-19=16 times as much heat. And if you want to raise the temperature of 193 grams in stead of just 1 gram, you will need 193 times as much heat. These two combined give us the following equation ... Now you can calculate the specific heat using this formula: c = Q / (m * ΔT) If you substitute the values from the previous steps you will have. c = -60000 J / (5 kg * -3 K) = 4200 J / kg*K which is water's normal heat capacity. If you find the manual calculation too difficult or if you want to check the accuracy of the specific heat value ...Specific heats of a great many substances have been measured under a variety of conditions. They are tabulated in books an on-line. We generally choose units of J/gram or KJ/Kg. The specific heat of liquid water is 4.184 J/g, which is also 4.184 KJ/Kg. Properties of air For ideal gases, the properties cρ, k, µ, and Pr are independent of pressure. The properties ρ, ν, and α at a pressure P (in atm) other than 1 atm are determined by multiplying the values of ρ at the given temperature by P and by dividing v and α by P.

The ratio of the speciﬁc heats, also called adiabatic index, is given by g = Cp Cv = 1 + 2 f. The ratio of the speciﬁc heats is 5/3 for monatomic ideal gas and 7/5 for diatomic gas. Its value for air is 1.4. This ratio is used to deﬁne (1) adiabatic process pVg = const, and (2) speed of sound in gases v = p gRT/M. • Specific Heat Capacities of an Ideal Gas--- 37 • The Adiabatic Process of an Ideal Gas--- 39 Ideal Gas Tables • Properties of Various Ideal Gases (at 300 K)--- 40 • Specific Heat Capacities of Air--- 41 • Critical Point Data of Various Substances--- 42 • Lee-Kesler Compressibility Chart--- 43 Air/Water Vapor Mixtures Calculation of thermodynamic state variables of air. lower limit for calculation: -150 C, 1 bar upper limit: 1000 C, 1000 bar. ... kinematic viscosity, specific enthalpy, specific entropy, specific isobar heat capacity cp, thermic conductivity, coefficient of thermal expansion, heat conductance, thermal diffusivity, Prandtl-number, coefficient ...Specific heat data are provided in Fig 3.9 and Tables A-19 through A-21.
