What is heat capacity state its SI unit?
Heat capacity of a substance is defined as the amount of heat energy given or released in changing the temperature of unit mass of substance by 1 oC. It is calculated as S=mΔTQ. Its SI unit is J/KgoC.
What is the units of heat capacity?
Joule per kelvin
Heat capacity/SI units
What is the symbol of molar heat capacity?
cn
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. where Q is heat and ΔT is the change in temperature.
How do you find molar heat capacity?
Molar heat capacity is the amount of heat required to raise the temperature of 1 mole of a substance by 1 unit & is calculated by dividing heat capacity by the total number of moles.
What is heat capacity Short answer?
heat capacity, ratio of heat absorbed by a material to the temperature change. It is usually expressed as calories per degree in terms of the actual amount of material being considered, most commonly a mole (the molecular weight in grams). The heat capacity in calories per gram is called specific heat.
What is the molar heat capacity of iron?

Is molar heat capacity the same as specific heat?
Molar heat capacity is a measure of the amount of heat necessary to raise the temperature of one mole of a pure substance by one degree K. Specific heat capacity is a measure of the amount of heat necessary to raise the temperature of one gram of a pure substance by one degree K.
What is the molar heat capacity of table salt?
Water has a specific heat capacity of 4.18 kJ/kgK while salt (NaCl) has a specific heat capacity of 0.88 kJ/kgK.
What is molar heat capacity Class 11?
Molar heat capacity of a substance is defined as the amount of heat required to raise the temperature of 1 mole of a substance through 1° C. …
What is molar heat capacity at constant pressure?
Molar specific heat capacity at constant pressure is defined as the amount of heat energy required to raise the temperature of one mole of a substance through 1K or 1∘C at constant pressure. It is denoted by CP .
