heat capacity vs specific heat

Who are the experts?Our certified Educators are real professors, teachers, and scholars who use their academic expertise to tackle your toughest questions. Using the same example, 50 grams of iron will have the same specific heat as 100 grams of iron. Educators go through a rigorous application process, and every answer they submit is reviewed by our in-house editorial team. Already a member? At room temperature, for example, water has a specific heat of about 4200 J kg-1 oC-1.

Top subjects are Science, Math, and History. ©2020 eNotes.com, Inc. All Rights Reserved. Specific heat gives the heat capacity per kilogram of a substance.

Heat capacity is directly proportional to the mass of an object.

Because of this, thermal capacity is a measurable physical quantity.

Summary: 1.“Heat capacity” is an extensive variable while “specific heat” is an intensive variable. 3.“Specific heat” is more suitable … Because of this, thermal capacity is a measurable physical quantity. Heat capacity gives the amount of energy required to raise the temperature of a given sample of a substance by 1 o C. Specific heat gives the heat capacity per kilogram of a substance. 1. Specific Heat is directly proportional to the mass of the object or substance, whereas heat capacity doesn’t depends upon the mass. The key difference between heat capacity and specific heat is that heat capacity is dependent on the amount of substance while specific heat capacity is independent of it.

Specific heat () describes the amount of heat required to raise the temperature of a kilogram of a substance by 1 oC or 1 K. In some fields, the amount of heat required to raise temperature by 1 gram is also often considered.

This means that it varies per amount of the substance.

This fact is extremely useful in regulating temperatures of “warm-blooded” animals. The unit for thermal capacity is J/K (joule per Kelvin) while that of specific heat is J/Kg (joule per Kelvin per gram).

Specific heat capacity (C) is defined as the amount of heat absorbed (Q) in order to increase the temperature (∆T) by 1 unit, of a unit mass(m).

This is a comparatively high specific heat, meaning that the amount of energy required to raise the temperature of water by a given amount is also quite high. This means that the heat capacity varies, as well. 2.“Specific heat” has a unit of mass in its equation as recommended by the International Standards of measurement.

For example, 50 grams of iron will have a different thermal capacity as 100 grams of the same substance. What are the four basic functions of a computer system? Another commonly used parameter is the molar specific heat which is the ratio of heat/thermal capacity with the number of moles (instead of the mass of the object).

For instance, a sample containing twice the amount of substance as another sample would require twice the amount o…

How do you calculate the number of neutrons? The descriptions of heat capacity and specific heat work in the same way for a reduction in temperature by 1 oC or 1 K. Specific heat capacity itself changes as with the temperature. Difference Between Acceleration and Deceleration, Difference Between Sonogram and Ultrasound, What is the Difference Between Roll On and Stick Deodorant, What is the Difference Between Thread and Yarn, What is the Difference Between Moissanite and Cubic Zirconia, What is the Difference Between Downhill and Enduro, What is the Difference Between Cause and Reason, What is the Difference Between Bromides and Sulphites. Specific heat, on the other hand, is a derived quantity by getting the ratio of the heat/thermal capacity to the mass of the object of interest. What would happen to the life of a cell if there was no Golgi apparatus. The main difference between specific heat and heat capacity is that specific heat is the amount of energy needed to raise the temperature of a given sample by 1 K while heat capacity is the amount of energy needed to raise the temperature of 1 kg of substance by 1 K. Heat capacity describes the amount of heat needed to raise the temperature of a given sample of a substance by 1 degree Celsius or 1 Kelvin (raising the temperature by 1 oC is the same as raising the temperature by 1 K).

It is the parameter that can be measured experimentally. Home » Science » Physics » Difference Between Specific Heat and Heat Capacity.
