What is molar specific heat of gas?

Molar Specific Heat of Gas at Constant Pressure: The quantity of heat required to raise the temperature of one mole of gas through 1K (or 1 °C) when pressure is kept constant is called molar specific heat at constant pressure. It is denoted by CP. Its S.I. unit is J K-1 mol-1.

What is the difference between specific heat and specific heat capacity?

Main Differences Between Specific Heat and Heat Capacity Specific heat is the amount of heat energy required by a unit of mass of a substance to raise its temperature through1℃ or 1 k. On the other hand, heat capacity is the amount of heat energy required by a substance to raise its temperature by 1℃ or 1 K.

What is specific heat of a gas?

The specific heat of a gas at constant pressure is the amount of heat required to raise the temperature of one mole of a gas by unit temperature at constant pressure.

Why are the specific heat capacities of metals so different while the molar heat capacities are similar?

The specific heat capacity of different substances vary for the same reason that different substances have different melting and boiling points to one another. If the bonds between atoms are stronger, it will require more energy to heat up the substance.

What is molar specific heat write its unit and also definition of molar specific heat and constant pressure and constant volume?

Molar heat capacity or molar specific heat capacity is the amount of heat energy required to raise the temperature of 1 mole of a substance. In SI units, molar heat capacity (symbol: cn) is the amount of heat in joules required to raise 1 mole of a substance 1 Kelvin. cn = Q/ΔT.

Why there are two molar specific heat for gas?

the specific heat is the amount of energy needed to raise the temperature of one mole of gas by 1 kelvin. the reason gasses have two specific heats because they are not stable, they change more than liquids and solids. therefore, when the volume held constant we get the heat capacity at constant volume(Cv).

What is the relationship between heat capacity and specific heat?

The heat capacity and the specific heat are related by C=cm or c=C/m. The mass m, specific heat c, change in temperature ΔT, and heat added (or subtracted) Q are related by the equation: Q=mcΔT. Values of specific heat are dependent on the properties and phase of a given substance.

Why do metals differ in specific heat?

It is the amount of energy needed to heat up a certain amount of a substance (usually a gram) by one degree. Its units are J/(g K). The heavier elements contain fewer atoms to absorb the energy per gram of material and therefore tend to have lower specific heat capacities.

Why specific heat is different for different materials?

Each substance will have a different mass, so when the amount of heat and the change in temperature are held constant, the only variable is the mass. Therefore, because mass is the only variable, so because substances have different masses, they will have different specific heats.

What is molar specific heat write its unit?

The molar heat capacity of a chemical substance is the amount of energy that must be added, in the form of heat, to one mole of the substance in order to cause an increase of one unit in its temperature. The SI unit of specific heat is joule per kelvin per mole, J⋅K−1⋅mol−1.

What is the unit of specific heat?

specific heat, the quantity of heat required to raise the temperature of one gram of a substance by one Celsius degree. The units of specific heat are usually calories or joules per gram per Celsius degree.
