what is the difference between specific heat and molar heat capacity?

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.

Specific heat values for liquids will never vary for different ranges of temperature. The specific heat of a gas may be measured at constant pressure. - is accurate when discussing specific heat.

Both mass and volume are physical properties, not chemical. Boiling point is the temperature when a substance start to boil. Boiling is also a physical property, chemical change isn't supposed. Malleability is the extent to which a substance may change its form without breaking.

Cp is "Specific Heat in constant pressure". ... Cv is "Specific heat in constant volume". This means it is the amount of heat required to increase temperature by 1 dgree celcius, when heat is given at constant volume. So, Cp and Cv is used according to the heat supplied.

Density is simply a ratio between the mass of a sample and it's volume. Specific Heat is a measure of how much thermal energy is required to raise the temperature one degree Celsius of one gram of the material. There is no correlation between the two quantities.

Thermal conductivity is the ability to transfer heat while the specific heat is the ability to hold a particular amount of heat. All conductors have relatively low specific heat capacity but for nonconductors have some high value for specific heat capacity.

Thermal conductivity describes the ability of a material to conduct heat, and the specific heat capacity tells how much heat energy is absorbed or released depending on the temperature difference and mass [1]. These values are needed, among other uses, in thermal performance calculations.

Specific Conductivity is equal to the Molar Conductivity, multiplied by Molarity of the solution.

The key difference is related to the size. In bulk material the physical properties are independent of its size but when yo go to nanometer scale it could be totally different and dependent on size and also shape.

The heat capacity of a substance is the amount of heat required to raise the temperature of a defined amount of pure substances by one degree (Celsius or Kelvin). The calorie was defined so that the heat capacity of water was equal to one.

Molarity (M) is defined as the number of moles of solute (n) divided by the volume (V) of the solution in liters. It is important to note that the molarity is defined as moles of solute per liter of solution, not moles of solute per liter of solvent. ... Just divide moles of solute by volume of solution.

Molecular weight is the mass of one molecule of a compound, while molar mass is the mass of one mole of a compound.

The heat capacity at constant pressure CP is greater than the heat capacity at constant volume CV , because when heat is added at constant pressure, the substance expands and work. QV = CV △T = △U + W = △U because no work is done. Therefore, dU = CV dT and CV = dU dT .

Heat capacity is the amount of heat necessary to raise the temperature of exactly 1 mole of a substance by exactly 1°C. Specific heat is the amount of heat necessary to raise the temperature of exactly 1 mole of a substance by exactly 1°C.

Molarity and Normality are two important terms which often we use to do calculations. In fact, normality is to be defined only during a chemical process. 1M is 1 molar but, 1N is 1 normal where equivalent mass is the criterion in later case.

The specific heat capacity of a material is the energy required to raise one kilogram (kg) of the material by one degree Celsius (°C). The specific heat capacity of water is 4,200 joules per kilogram per degree Celsius (J/kg°C).
