Heat capacity
Heat capacity is also called as thermal capacity and (generally denoted by a capital C or Cth) is defined as ability of substance is the amount of heat energy required to consume with the intention of raise its temperature. Heat-capacity is denoted as units of joules (J) per Kelvin (K).
The heat capacity of water is nothing but the quantity of heat required to raise its temperature a certain quantity. Water has the very high specific heat index and the second greatest with all the heteroatom species (later than ammonia) over and above a high heat of vaporization (40.65 kJ/mol or 2257 kJ/kg at the common boiling point), both of which are a consequence of the extensive hydrogen bonding among its molecules. Usually water will absorb lot of heat before it commences to get hot. I like to share this Specific Heat Capacity Equation with you all through my article.
Each pure matter involved in a chemical reaction has a exclusive heat-capacity and the heat-capacity of (1 mol) of pure matter is called as its molar heat capacity (and its expressed as J/mol-K pr J/mol-°C). The heat-capacity of (1g) of matter is identified as its specific heat (J/g-K). the following heat capacity formula used as the specific heat of matter, the mass of the matter, the temperature change and how much energy of heat required to invest in the system. The quantity of heat energy (q) is lost or gained by a material is equal to the weight of material (m) multiplied by its specific heat-capacity (Cg) multiplied by the change in temperature (final temperature – initial temperature).
q = mCpDT or q = m x Cg x (Tf-Ti)
Whereas;
q = quantity of heat (expressed as joules or calories)
m = mass in grams (g)
DT – Tf – Ti (final – initial)
Cp = specific H capacity (J/g °C)
By using this equation the quantity of heat energy lost or gained by a material can be used to calculated by the moles of material.
q = n x Cn x (Tf – Ti)
Whereas;
q = quantity of heat energy lost or gained by material
n = moles of material
Cn = molar H capacity
Tf = final temperature
Ti = initial temperature

Specific heat capacity of water at room temperature with pressure is approximately 4.2 J/g°C. This means to raise 1 gram (1 mL if we would to a certain extent think of the equivalent volume of 1gram of water) of water at 1 degree Celsius to required for 4.2 joules of energy and it’s essentially quit large. At a room temperature the specific Ht capacity of water vapor is still higher. At a room temperature the Ht capacity of hydrogen gas is 14.3 J/g °C. Find here with some of value mention specific heat capacities of different materials.
