Examples Of Specific Heat

And t is the temperature change of the contents.

Examples of specific heat. The specific heat is the amount of heat necessary to change the temperature of 1 00 kg of mass by 1 00ºc. In addition we will discuss specific heat specific heat formula its derivation and solved examples in this topic. Examples of specific sensible and latent heat specific heat. Its si unit is j kg k or j kg c.

1 calorie gm c 4 186 j gm c. A hot water bottle cools down from 80 c to 20 c releasing 756000j of thermal energy. The sensible heat is the amount of heat that can receive a body without affecting its molecular structure. Ccontents is the specific heat capacity of the contents.

That means 1 kg of water will absorb 4182 joules of energy for raising its temperature by 1 k or 1 c. But specific heat is a concept that very few people know about. Scientifically water s specific heat is written as. Use the formula q mcδt where q heat energy m mass c specific heat δt change in temperature putting the numbers into the equation yields.

C 487 5 j 25g 50 c c 0 39 j g c. Some other examples of specific heat capacities are. The symbol c stands for specific heat and depends on the material and phase. The specific heat of a substance is the amount of heat that must be supplied to a unit of mass of that.

Also we use specific heat to raise the temperature of an object by degree. An example of a high specific heat is water s specific heat which requires 4 184 joules of heat to increase the temperature of 1 gram of water 1 degree celsius. The specific heat capacity of water is 4182 j kg k. Brick will take much longer to heat up.

The specific heat capacity of aluminium is 913 j kg c. Calculate the thermal energy stored in the plate when the temperature rises from 20 c to 200 c. Specific heat in a sentence 1. 487 5 j 25 g c 75 c 25 c 487 5 j 25 g c 50 c solve for c.

I hope you have clearly understood the definition of specific heat capacity. The specific heat capacity of water is 4200 j kg c. An iron has an aluminium plate with a mass of 1 5kg. Furthermore the specific heat of different elements differs from each other.
