In olden days, scientists had not attained a state to realize the relation between heat and mechanical energy. So in that situation they have coined a word calorie for the unit of heat. One more point that only cgs system was active in those days. Calorie is defined as the heat required to rise the temperature of one gram of water through one degree celcius. If s calorie of heat is required to rise the temperature of one gram of any substance then s is said to be the specific heat of the substance.
Later science got good advancement, heat was also measured in terms of the unit of mechanical energy ie joule. So the amount of heat energy in joules to rise the temperature of one gram of water was found to be 4.18 joule. Hence mechanical equivalent of heat is said to be 1 calorie = 4.18 joule
So the heat energy in joule required to rise the temperature of one kilo gram (not one gram) of substance is defined as the specific heat capacity. Capacity has been added along with specific heat. Many modifications gradually came into the scene. Absolute scale was found and unit for temperature kelvin got introduced.
So just heat, one gram and celcius all have become obsolete. They have been replaced by energy, one kilo gram and kelvin respectively. This is also to be treated as evolution in probing the secret of nature in a systematic way.
Hence in case of water, its specific heat capacity was found to be 4180 joule/kg/K.
yes
The amount of energy required to raise 1 kg of a substance by 1 degree Celsius is called the "Specific Heat Capacity," or just specific heat, of a substance. This is an intensive property of the particular substance.
To lower the temperature of 1 gram of water by 1 degree Celsius would be to remove 1 calorie.
One calorie is needed to heat 1 gram of water 1 degree Celsius
Is the amount of energy that is required to change the temperature of 1kg of a substance by 1 degree Celsius with no state change.
The specific heat is the amount of heat required to raise the temperature of 1 g of substance by one degree Celsius or one Kelvin.
liquid
Every substance has a specific heat. The definition of specific heat is: The amount of energy, usually measured in calories, needed to raise the temperature of one gram of a certain substance by one degree Celsius.
Ton Of Refrigeration : Is the refrigerating effect required to reduce the temperature of one ton of water from zero degree Celsius (liquid stage) to zero degree Celsius (solid stage) in 24 hour. Kiran.
chemicals with temperatures 0f 38 degree Celsius below 0
Metallic
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.
Specific Heat is the energy required to raise 1 g of any specific object by 1 degree Celsius.
