SPECIFIC HEAT CALCULATOR
Specific Heat calculator is a type of calculator that computes the specific heat of an item based on the heat energy applied, the mass of the object and the change in temperature. Specific Heat is the heat transfer capacity per unit mass of a material.An object’s heat capacity (symbol C) is defined as the ratio of the amount of heat energy transferred to an object to the resulting increase in temperature of the object.This three components heat energy, mass and temperature varies from objects to objects
. examples of different specific heat of different objects
ice | 2100 j/(Kg.K) |
water | 4,200 j/(Kg.K) |
watervapor | 2000 j/(Kg.K) |
basalt | 840 j/(Kg.K) |
granite | 790 j/(Kg.K) |
aluminium | 890 j/(Kg.K) |
iron | 450 j/(Kg.K) |
copper | 380 j/(Kg.K) |
lead | 130 j/(Kg.K) |

instruction to use specific heat calculator
Enter the following while Choosing units to choose.
(Q) Heat Energy Applied
(m) Mass of Object
(ΔT) Change in Temperature
Specific Heat (C): The specific heat is returned in Joules per gram*degrees Celsius ( J/(g•C) ).
Specific Heat (C): The specific heat is returned in Joules per gram*degrees Celsius ( J/(g•C) ).
The Math / Science
The formula for specific heat using change in temperature is:
C=Qm⋅ΔTC=Qm⋅ΔT
where:
C = Specific Heat
Q = Energy Applied
m = mass of object
ΔT = Change in Temperature
The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. The relationship between heat and temperature change is usually expressed in the form shown where C is the specific heat.
application of specific heat
The specific heat capacity indicates the ability of a substance to store heat.Specific heat calculator has alot of applications in our daily lives this applications are: Constructing kettle handlers, insulators and oven covers specific heat is applicable. because, a high amount of heat will cause only a small change in temperature .Substances having a small specific heat capacity, are very useful as material in cooking instruments such as frying pans, pots, kettles and so on, because, when small amount of heat is applied it will heat quickly hence specific heat capacity being used,Water used in fire fighting also requres specific heat capacity and also due to high specific heat it absorbs a large amount of heat without appreciable rise in temperature. Oceans transport is the heat away from the equator areas and helps to moderate the climates there also hence heat capacity being applicable.
TECHQNICS OF DETERMING SPECIFIC HEAT CAPACITY
1. (Q) Heat Energy Applied
The definition of heat energy is the transfer of energy from one thing to another by kinetic energy, usually causing a higher temperature.
2.(m) Mass of Object
Mass (symbolized m) is a dimensionless quantity representing the amount of matter in a particle or object. The standard unit of mass in the International System (SI) is the kilogram (kg).Mass is measured by determining the extent to which a particle or object resists a change in its direction or speed when a force is applied.
3.(ΔT) Change in Temperature
Change in temperature is the the amount of heat to be supplied to an object to produce a unit change in its temperature. The SI unit of heat capacity is joule per kelvin (J/K)./
the symbol of calculating the temperature of specific heat capacity is
Q = mcΔT
where Q is the change in temperature
m is the mass of an object
c is the specific heat capacityoffice
Examples:
1. What is the specific heat capacity value of copper?
solution
You can use this value to estimate the energy required to heat a 100 g of copper by 5 °C, and heat energy required 192.5j i.e
m=100g
ΔT=5 °C
Q= 192.5j
=385 j/kg K
The specific heat of copper is 385 J/kg K.
2. What is the specific heat capacity value of aluminum?
solution
You can use this value to estimate the energy required to heat a 500 g of aluminum by 5 °C and energy applied is 22242.5 J .
M=500g
ΔT=5 °C
Q= 22242.5 J .
The specific heat of aluminum is 897 J/kg K. T
