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?

What is xenon's specific heat?
Xenon, a noble gas, has a specific heat capacity of approximately 0.159 J/g·K at constant pressure (Cp) and about 0.124 J/g·K at constant volume (Cv). This means it requires 0.159 joules of energy to raise the temperature of one gram of xenon by one Kelvin under constant pressure conditions. Its relatively low specific heat reflects its status as a heavy and inert gas.
What is the specific heat constant of oxygen?
heat constant = mass * specific heat capacity * temperature change
Why general gas equation is used in the proof of cp-cvR?
The general gas equation, PV = nRT, is used in the proof of the specific heat capacities relationship (Cp - Cv = R) because it helps relate the pressure, volume, and temperature of a gas to its moles and universal gas constant, allowing for the derivation of Cp and Cv in terms of these properties. This relationship is then utilized to show that the difference between the specific heat capacities at constant pressure and constant volume is equal to the universal gas constant.

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.
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 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.
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.
Define molar specific heats of a gas?
Molar specific heats of a gas refer to the amount of heat required to raise the temperature of one mole of the gas by one degree Celsius (or Kelvin) at constant pressure or constant volume. The specific heat capacity at constant pressure is denoted as Cp, and at constant volume as Cv. These values are important in understanding the thermodynamic behavior of gases.
What is Regnault's Law?
Regnault's Law is a statement in physics that says that the specific heat of a gas at constant pressure is the same whatever the pressure.
What is xenon's specific heat?
Xenon, a noble gas, has a specific heat capacity of approximately 0.159 J/g·K at constant pressure (Cp) and about 0.124 J/g·K at constant volume (Cv).
