Molar heat capacity is the amount of heat required to raise the temperature of one mole of a substance by one degree Celsius (or one Kelvin). It is an important thermodynamic property that reflects how a substance absorbs heat. The units of molar heat capacity are typically expressed in joules per mole per degree Celsius (J/mol·°C) or joules per mole per Kelvin (J/mol·K).

How do you measure molar heat capacity?
Specific heat is the heat capacity divided by the heat capacity of water, which makes it dimensionless. To obtain molar heat capacity from specific heat for a material of interest, simply multiply the specific heat by the heat capacity of water per gram [1 cal/(g*C)]and multiply by the molecular weight of the substance of interest. For example, to obtain the molar heat capacity of iron Specific heat of iron = 0.15 (note there are no units) Molar heat capacity of iron = 0.15*1 cal/(g*C)*55.85 g /gmole = 8.378 cal/(gmole*C)
What is the specific heat capacity for selenium?
The molar heat capacity of selenium is 25,363 J/mol.K.
What units does molar heat of vaporization have?
In SI units: kJ/kmol
What is another way to say heat capacity?
Another way of stating this, is that the volume-specific heat capacity (volumetric heat capacity) of solar elements is roughly constant. The molar volume of the solid.
What is the heat capacity of 165g of liquid water?
The specific heat capacity of liquid water is 4.184 J/g°C. To find the heat capacity, you multiply the mass of the water (165g) by the specific heat capacity. So, the heat capacity of 165g of liquid water is 688.56 J/°C.

Molar heat capacity of water?
Molar heat capacity of liquid water = 75.3538 Molar heat capacity = molar mass x specific heat
Is molar heat capacity intensive or extensive?
Molar heat capacity is an extensive property because it depends on the amount of substance being considered.
What is the specific heat capacity for selenium?
The molar heat capacity of selenium is 25,363 J/mol.K.
What is the symbol for molar heat capacity and how is it calculated?
The symbol for molar heat capacity is (Ctextm). It is calculated by dividing the heat capacity of a substance by the amount of substance in moles. Mathematically, it is expressed as (Ctextm fracCn), where (C) is the heat capacity and (n) is the amount of substance in moles.
What units does molar heat of vaporization have?
In SI units: kJ/kmol
How do you prove that the molar heat capacity at the constant volume?
no be quiet
What is the difference in specific heat between hydrogen and oxygen molecules?
The molar heat capacity of hydrogen (H2) is 28,835 J/mol/K.The molar heat capacity of oxygen (O2) is 29,378 J/mol/K.
What is molar heat?
Different substances have varied molar heat capacities. The molar heat capacity of a substance refers to the amount of heat energy needed to raise 1 mole of that substance by 1 degree Celsius.
What is another way to say heat capacity?
Another way of stating this, is that the volume-specific heat capacity (volumetric heat capacity) of solar elements is roughly constant. The molar volume of the solid.
What are the units specikfic heat is commonly expressed in?
Specific heat capacity is the heat capacity per unit mass, and is expressed as
What is the heat capacity of 165g of liquid water?
The specific heat capacity of liquid water is 4.184 J/g°C. To find the heat capacity, you multiply the mass of the water (165g) by the specific heat capacity. So, the heat capacity of 165g of liquid water is 688.56 J/°C.
