Imagine 1 kg of water. This has a heat capacity. Now if you have 1000kg of water the heat capacity is obviously greater.
The Specific Heat Capacity is a material constant. It specifies a set quantity. For water it is 4.184 kiloJoules per kilogram per Kelvin.

What factor most influence the amount of energy needed to change the temperature of a substance?
specific heat capacity
Which substance having high specific heat capacity?
A common substance with a high specific heat is water. There are a few substances that have a higher heat capacity than water, though, such as lithium and ammonia.
When does the thermal capacity of a substance become equal to its specific gravity?
Thermal capacity is equals to the product of the mass of the body and its specific gravity. Thus, specific heat is equals to the thermal capacity divided by the mass of the body. Now, if the mass of tue body be unity then specific heat will be equals to the thermal capacity of the body. So, thermal capacity of unit mass of a substance is equals to its specific heat
What is the quantity of heat energy required to raise the temperature of a unit mass of a substance?
If the substance is water, this is the kilocalorie (1000 calories). One calorie is the heat to raise one gram of water by 1 deg C. Other substances don't have the same specific heat capacity as water, so you have to correct for that, first find out the heat capacity (specific heat) for the substance you are dealing with.
What property of a substance does its specific heat capacity describe?
How much heat it takes to raise the temperature
What is used to find the specific heat capacity of a substance?
The equation for specific heat is: C = q/temp. change x mass. C is a substance's specific heat, which is a constant for every substance. q is its heat capacity in joules, temp. change is the change in temperature in degrees Celsius, and mass is in grams.
Is specific heat capacity inversly proportional to its mass?
No. Specific heat capacity is 'normalized' with respect to mass, so it's a property of the substance, regardless of the mass of the sample.
What is the amount of energy that it takes to raise temperature of 1gram of substance by 1 degree kelvin?
Heat energy, although almost any energy will become heat. The amount of energy required depends on the substance.
What is the specific heat capacity of jam?
The specific heat capacity is the energy density of a substance. Since jam has a higher specific heat capacity than the pie crust it is contained in, this is why the contents of a pie are always much hotter than the pie itself.
Would two different liquids stored in the fridge for the same period of time be equally cold?
No. They would lose (or absorb) the same amount of heat, but their temperatures would be different.Every liquid has a unique specific heat capacity.The specific heat capacity of a substance is the amount of heat required to heat unit mass (1 kg) of that substance through 1°Celsius.So, liquids with different specific heats would show different change in temperature after losing the same amount of heat.For example, a liquid with a lower specific heat capacity would require lesser heat to change it's temperature while one with a higher specific heat capacity would require more heat.Hence, since the heat lost would be the same, the liquid with a lower specific heat capacity would cool more and have a lower temperature.
Why specific heat capacity increase with temperature?
Specific heat capacity is by definition a per-unit-mass property. Therefore it does not depend on the mass of the substance.
How specific heat different from heat capacity?
Specific heat capacity is the amount of energy required to raise the temperature of one unit mass of a substance by one degree Kelvin. Eg. The specific heat capacity of water is 4.18 joules per gram. So you need to transfer 4.18 joules of energy to one gram of water in order to raise it by one degree K Temperature on the other hand is the average kinetic energy of the particles in a substance.
