The specific heat capacity of a material is a measure of the amount of energy required to raise the temperature of a specific quantity of that material by a specific amount. The units of specific heat capacity are kilojoules per kilogram kelvin. The specific heat capacity of paper is 1.4 kilojoules per kilogram kelvin.

Likewise, what is the equation for specific heat capacity?
The units of specific heat capacity are J/(kg °C) or equivalently J/(kg K). The heat capacity and the specific heat are related by C=cm or c=C/m. The mass m, specific heat c, change in temperature ΔT, and heat added (or subtracted) Q are related by the equation: Q=mcΔT.

What is the specific heat capacity of ethanol?
At ambient pressure and temperature the isobaric specific heat, CP, of liquid ethanol is 2.57 [kJ/kg K] or 0.614 [Btu/lb °F] = [cal/g K], while the isochoric specific heat, CV, is 2.18 [kJ/kg K] or 0.520 [Btu/lb °F] = [cal/g K]. However, the specific heat - CP and CV - will vary with temperature.

This quantity is known as the specific heat capacity (or simply, the specific heat), which is the heat capacity per unit mass of a material . Experiments show that the transferred heat depends on three factors: (1) The change in temperature, (2) the mass of the system, and (3) the substance and phase of the substance .Why is specific heat capacity important?
Specific heat capacity is a measure of the amount of heat energy required to change the temperature of 1 kg of a material by 1 K. Hence it is important as it will give an indication of how much energy will be required to heat or cool an object of a given mass by a given amount.Can specific heat capacity be negative?
If the system loses energy, for example, by radiating energy into space, the average kinetic energy actually increases. If a temperature is defined by the average kinetic energy, then the system therefore can be said to have a negative heat capacity. A more extreme version of this occurs with black holes.How do I calculate specific heat?
Specific Heat- For a mass m = gm = kg.
- with specific heat c = cal/gm°C = joule/gm°C,
- initial temperature Ti = °C = K = °F.
- and final temperature Tf = °C = K = °F,
- Q = calories = kcal = x 10^ calories.
- Q = joules = x 10^ joules.
