### heat capacity

What exactly is heat capacity, and why is it a state property?

### Re: heat capacity

Specific heat capacity is the amount of heat required to raise 1 gram of a substance by one degree (i.e. 1 degree Kelvin). It is a state property because it is a property independent of how the substance was prepared (in this case heated).

### Re: heat capacity

Heat capacity refers to the ratio of the amount of heat energy added or removed from an object to the resulting increase its temperature. This makes it a state property because it does not matter how the heat was added but rather depends on the initial and final states.

### Re: heat capacity

Heat capacity just depends on the final and initial values that is why it is a state property.

### Re: heat capacity

Heat capacity allows us to quantify a substance's ability to absorb heat energy. It is also important to note the difference between heat capacity and specific heat, as specific heat focuses solely on one unit of mass.

Heat capacity is the amount of heat needed to increase the temperature of one gram of a substance by one degree. It has a state property because it is independent of how the substance was prepared.

### Re: heat capacity

Heat Capacity is measurement of heat absorbed or released. Since temperature change is directly proportional to the heat added, with the heat capacity as the proportionality constant, we can use the heat capacity to convert the temperature change into energy.

### Re: heat capacity

Heat capacity is used to measure the heat absorbed or released when a given kind of materials experience a change of temperatures. It could be expressed by the equation: Q=mc*delta T (T is in Kelvin temperature scale). The materials with higher heat capacities require more heat to have a certain temperature change; while the materials with lower heat capacities require less heat to have a certain temperature change.
