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?
Density Specific Volume Pressure Temperature Viscoisy Gas Constant Heat Specific
What is specific heat at constant pressure of honge oil?
The calorific value is 8 742 kJ/kg.
Why is high specific heat importamt to life?
Water has a high specific heat due to hydrogen bonding, which increases intermolecular forces between molecules
What is the amount of heat needed to change 1 kg of a specific material from liquid to vapor at a constant temperature?
Latent
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 is molar specific heat of solid at constant volume?
This is the necessary heat to raise the temprataure of 1 mol with 1 kelvin, at constant volume.
Why is ocean temperature more constant than air temperature?
The specific heat of water is greater than the specific heat of air.
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 are the properties of mass?
Density Specific Volume Pressure Temperature Viscoisy Gas Constant Heat Specific
Is specific heat the same as specific gravity?
No. Specific heat is the amount of heat required to raise 1 kg of material by 1 K at constant pressure, while specific gravity is the ratio of the material's density to a reference density (typically water).
What characteristic of water contributes to the relatively constant temperatures of the oceans?
High Specific Heat
Why has a gas two values of molar heat capacities?
Gasses have two specific heat capacities because the boundary conditions can affect the number by up to 60%. Therefore, a number is given to each boundary condition: isobaric (constant pressure) or isochoric (constant volume). In an ideal gas, they differ by the quantity R (the gas constant - the same one you use in the ideal gas law): Cp = Cv + R where Cp is the isobaric molar heat capacity (specific heat) and Cv is the isochoric molar heat capacity.
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 total heat energy supplied in isobaric process?
An isobaric process is one occurring at constant pressure (we are talking about gases). So the specific heat to use is Cp, the specific heat of the gas at constant pressure. To get the total heat energy you obviously need to also know the quantity of the gas involved, and the change in temperature.
What constant is needed to determine the energy needed to warm the water to 25.C?
The answer is SPECIFIC HEAT!
Why the molar specific heat at constant pressure is larger than the molar specific heat at constant volume?
This question is wrong. Heat capacity at constant pressure is more than that at constant volume. And Heat capacity at constant pressure - Heat capacity at constant volume= R Cp - Cv= R ,where R is universal gas constant.
