Specific heat capacity is the amount of heat
energy required to increase the temperature of a substance per unit of mass. The
atoms and molecules of substances gain kinetic energy and their speed increases
the average kinetic energy of these particles is proportional to the
temperature of the substance. When a material is heated, causing its
temperature to rise, this is because the average value of the kinetic energy of
the atoms or molecules has increased. The specific heat capacity of a material
is a physical property. However, the heat capacity differs for different
materials and mass. For example, if you heat water and oil in a pan with the
same mass the oil temperature increases faster than water therefore the oil has
gained energy. This means that also, specific heat capacity is an extrinsic
property while resistivity is an intrinsic. This means that the amount of
energy depends on the mass of the object, the temperature change and the
specific heat capacity.  

The specific heat capacity for water is very
high because it requires a large amount of heat to get heated and also a large
amount of time to get cooled down again. Water acts as a cooling agent for us.
It’s useful for us that the specific water is very high since it acts as
cooling agent in the industry( cars, nuclear cars and machines). The water
absorbs the heat in these machines and helps the machines not to get
overheated. The specific heat capacity also acts as natural cooling agent; it
helps in the formation of land breeze.

The ‘Q’ is the amount of heat exchange in a reaction is
equal to the heat capacity of the substance times the change in temperature for
the substance, or virtually the heat exchange equal to the specific heat of the
substance times the grams of the substances present times the change in
temperature. This enables scientist to learn about heat transfer, using the
process called calorimeter.

C = Q/M__T

Heat energy is generated by the voltage
difference is equal to to the heat required to raise the temperature of the aluminium.
Different fluids store heat differently and we can describe this by quantity of
heat capacity.

Linking to the scenario, a cars motor gets
very hot and is very important to know that heat is dispersed through the engine.
If you have poor heat management, it can lead to engine failure and could
explode. This is why specific heat capacity is vital when designing and
building engines and large machinery.

has a high specific heat capacity, and is very effective when acting as a
cooling agent in engines. water has a high specific water  due to presence of intermolecular hydrogen
bonding in it The amount of heat supplied is used initially to break the
bonding reason water has high specific heat capacity. A large amount of heat is
used to break the hydrogen bonds rather than increasing the water’s movement

 A water pump flows the water around the
engine, and the heat produced by the engine is absorbed by the water. That hot
water that circulates around the engine walls is then forced into the cars
radiator where the heat from the water is released through the cooling fan.
Engine parts constantly expand and contract due to the fluctuation in heat
within the engine. That is why it’s important to put metals with similar
specific heat capacities are put together, because if one metal heats up faster
than the other and they’re connected, and one expands faster than the other,
then cracking and splitting may occur. Materials that have lower specific heat
capacities are prone to gaining more heat, or heat up quicker even if a smaller
amount of heat energy is applied to that material. These materials are very
useful for cooking appliances. Despite the fact that the heating element of a
kettle has a low specific heat capacity, the outer casing of kettle would have
to have a higher specific heat capacity so that you don’t burn your hand.

In a cooking pot, it would generally have a
copper base, which has low specific heat capacity to absorb the heat. It’s also
very stable so that the pot, it would generally have a copper base

In a cooking pot, it would generally have a copper base, which has low
specific heat capacity to absorb the heat. It’s also very stable. Also, wood is
often used as the handles of the put due to woods low conductivity of heat.


To measure temperature the liquid and the material that is in the
thermometer must have low specific capacities for accurate measurements of
the temperature. The thermometer which has a specific heat capacity of 0.84 J/g
and the mercury which is the liquid in thermometers have a specific heat
capacity of 0.14 J/g.Thisis why mercury is used in thermometers.
