the chemical composition of air
78% almost nitrogen 20% oxygen and other gases 1%app.among all 1% argon has comparetive higher molar mass so taking that only to get approx.result.taking 100 grm air no of mols
nitrogen 5.5 diatomic gamma 1.4
oxygen .625
argon .05 mono atmic gamma 1.66
getting the ans by
(total mols of air-1)/x =summation (moles of gas y-1)/gomma of that gas
gas y is nitrogen oxygen & argon
specific heat at cnst pressure =gamma.8.314)/gamma -1
ans 15.35 j/mol

Why dual combustion cycle is called as limited pressure cycle?
In dual combustion cycle heat is added at constant volume which increases the efficiency of cycle, whereas heat addition at constant pressure limits the maximum pressure of the cycle.
Is the heat content of a system at a constant pressure?
Yes it is possible, for example when water freezes there is a point when the temperature remains constant however energy is released as the water condenses.
Heat engine utilizes low heat value of fuel or high heat value of fuel?
Heat engine utilizes low heat value of oil and also the fuel oil consumption for IC engine usually based on high heat value of oilby Shyam
What is the function of Wire Gauze?
it helps in providing constant heat
What happen if you heat steam?
If you heat steam under pressure you get "superheated steam" under higher than original pressure
What is the value of the of gamma in air?
The value of the specific heat ratio (gamma) in air is approximately 1.4 at room temperature. It represents the ratio of specific heats, which is the ratio of the heat capacity at constant pressure to the heat capacity at constant volume.
What is specific heat at constant pressure of honge oil?
The calorific value is 8 742 kJ/kg.
Is water have specific heat at constant volume or not?
Yes it has! the specific heat of water at constant volume is given by cV : Heat capacity at constant volume cP : Heat capacity at constant pressure : Thermal expansion coefficient : Isothermal compressibility : Density
What are the properties of mass?

Air expands according to the law pv1.3 a constant inside an enclosed cylinder find its specific heat?
c = specific heat .16902 = air at constant volume (since the cylinder size stays the same) 1.405 = specific heat of air at constant pressure divided by specific heat of air at constant volume *pressure doesn't necessarily stay constant as cylinder could be air compressor so c= 0.16902 (1.3-1.405/1.3-1) c= 0.169024 (-0.105/.3) c= 0.169024 (-0.35) c= -0.059158 or -0.059
What is the specific heat of argon in celsius?
The specific heat of argon is approximately 0.5205 J/g°C at a constant pressure of 1 atm.
What is the specific heat constant of oxygen?
heat constant = mass * specific heat capacity * temperature change
Why we use two type of molar specific heat?
For gases, there is heat specific heat capacity under the assumption that the volume remains constant, and under the assumption that the pressure remains constant. The reason the values are different is that when heating up a gas, in the case of constant pressure it requires additional energy to expand the gas. For solids and liquids, "constant volume" isn't used, since it would require a huge pressure to maintain the constant volume.
What is the significance of specific heat at constant pressure in thermodynamics?
The specific heat at constant pressure is important in thermodynamics because it measures how much heat energy is needed to raise the temperature of a substance without changing its volume. It helps in understanding how substances respond to changes in temperature and pressure, and is crucial in various engineering and scientific applications.
Why is cp used for solids instead of cv in heat transfer?
Specific heat capacity at constant pressure (cp) is used for gases because the heat transfer is generally at constant pressure conditions. For solids, heat transfer typically occurs at constant volume since solids do not easily change their volume. Therefore, the specific heat capacity at constant volume (cv) is used for solids in heat transfer calculations.
What is the adiabatic index of water and other liquids?
The adiabatic index of liquid water is about 4/3 or 1.33. This value represents the ratio of specific heat at constant pressure to specific heat at constant volume. Different liquids may have slightly different adiabatic indices depending on their molecular structure and interactions.
Why the molar specific heat at constant pressure is larger than the molar specific heat at constant volume?
The specific heat at constant pressure is larger than the molar specific heat at constant volume because if heat is added to a system it not only heats up but expands in volume. Therefore the system is doing work against the external pressure and the heat is not only stored as kinetic and potential energy but is also required to perform work. In general more heat can be stored in a system at constant pressure than one at constant volume. The specific heat at constant pressure is larger than the molar specific heat at constant volume because if heat is added to a system it not only heats up but expands in volume. Therefore the system is doing work against the external pressure and the heat is not only stored as kinetic and potential energy but is also required to perform work. In general more heat can be stored in a system at constant pressure than one at constant volume.
