What is Specific Heat Capacity
Specific Heat Capacity of Water is approximately 42 JgC. Specific heat tells you the amount of energy needed to raise each unit one degree.

SI units used for specific heat capacity in degree Celcius are JkgC and JgC.
. Heating Up Applications - Energy Required and Heat Transfer Rates - Energy required to heat up a substance. The definition of the calorie is based on the specific heat of water defined. 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.
Special heat capacity is measured in Jkg C or equivalently in Jkg K. Specific heat the quantity of heat required to raise the temperature of one gram of a substance by one Celsius degree. Specific Heat Capacity is the heat required to raise temperature of the unit mass of a given substance by a given amount.
Thus it takes 42 joules of energy to raise 1 gram of water by 1 degree Celsius. Mass of the substance. Heat capacity and Specific Heat capacity are always positive quantities.
For example the specific heat of water is 1 calorie or 4186 joules per gram per Celsius degree. Heat capacity ratio of heat absorbed by a material to the temperature change. The heat capacity in calories per gram is called specific heat.
When you find the heat capacity of one unit of something 1 gram 1 ounce 1 kilogram etc youve found this objects specific heat. Units of specific heat are calories or joules per gram per Celsius degreeFor example the specific heat of water. Heat Capacity - The amount of heat required to change the temperature of a substance by one degree.
The Specific Heat Capacity of a substance depends on three factors of a substance. The specific heat capacity of water vapour at room temperature is also higher than most other materials. The Scottish scientist Joseph Black in the 18th century noticed that equal masses of.
Metals - Specific Heats - Specific heat of commonly used metals like aluminum iron mercury and many more - imperial and SI units. The units of specific heat are usually calories or joules per gram per Celsius degree. Know that specific heat refers to the energy needed to raise one gram by one degree.
The SI unit of Specific Heat capacity is J kg1K1. Change in temperature of the. For water vapour at room temperature and pressure the value of specific heat capacity Cp is approximately 19 JgC.
In order to raise the temperature of a given substance by one degree Celsius the amount of heat it takes to warm that mass by one degree Celsius. Mass and volume are irrelevant for the specific heat capacity as opposed to the total heat capacity.
