What is the relationship between temperature change and the heat capacity at constant pressure?
The relationship between temperature change and heat capacity at constant pressure is that as the temperature increases, the heat capacity also increases. Heat capacity is a measure of how much heat energy is needed to raise the temperature of a substance by a certain amount, and it tends to increase with temperature because the substance can absorb more heat energy as it gets hotter.
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 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.
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.
What is the heat capacity of argon and how does it compare to other gases?
The heat capacity of argon is relatively low compared to other gases. It has a molar heat capacity of 20.85 J/molK at constant pressure and 12.48 J/molK at constant volume. This means that argon requires less energy to raise its temperature compared to other gases like nitrogen or oxygen.
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

How is specific heat of a substance different from the heat capacity?
Imagine 1 kg of water. This has a heat capacity. Now if you have 1000kg of water the heat capacity is obviously greater. The Specific Heat Capacity is a material constant. It specifies a set quantity. For water it is 4.184 kiloJoules per kilogram per Kelvin.
Molar heat capacity of water?
Molar heat capacity of liquid water = 75.3538 Molar heat capacity = molar mass x specific heat

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.
Why the molar specific heat at constant pressure is larger than the molar specific heat at constant volume?

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 allows water to maintain constant temperature and prevents sudden changes?
...HEAT CAPACITY ... sooo easssyy
What is the formula for calculating constant pressure of heat capacity?
Cp = ΔH/ΔT = (ΔU+pΔV)/ΔT Where Cp is heat capacity at constant pressure, ΔH is enthalpy change, ΔT is temperature change, ΔU is total internal energy change, and pΔV is pressure multiplied by change in volume.
