Specific heat refers to the exact amount of heat needed to make one unit of mass of a substance one degree warmer.Returning to our example, specific heat would identify exactly how much heat is required to make one unit of water, such as one cup, one degree warmer. Because heat is reall...
Molar Heat Capacity:The total amount of heat (in joules) required to increase the temperature of one mole of a substance by one Kelvin. Specific Heat Capacity:The total amount of heat (in calories) needed to raise the temperature of one gram of water by one degree Celsius. What is Heat ...
The temperature of an object is the measure of its 'hotness' or 'coldness' and reflects the thermal energy present in that object. Heat is a form of energy. When heat is absorbed by an object, its temperature increases. On the other hand, if heat is removed from an ...
The specific heat of water is a physical constant that dictates 4.186 Joules of energy are required to heat one cubic centimeter of water by one degree Celsius. Knowing the resistance of the heating element, one can calculate the dissipated power and calculate how much time it will tak...
In Chemistry, thermodynamics accounts for various parameters; If the heat of a reaction is studied, the enthalpy change is analyzed, Entropy and Gibbs free energy changes are two important parameters in a chemical reaction, Additional concepts are heat capacity and specific heat capacity of a ...
Electromagnetic energy in a light wave might be calculated in ergs. 12 Joule In terms of heat energy, one joule is the amount required to raise the temperature of a gram of water by 0.24 degrees Celsius. Heating a swimming pool during winter requires billions of joules. 7 Erg Ergs measure...
This is not an exact measurement, however, as the energy required depends slightly on the starting temperature of the water. The SI definition of calorie is now 1 calorie equals 4.184 joules. In specific terms, the energy would typically be measured as calories/gram (cal/g), kilocalories/kg...

The unit of heat is joule (J) in SI unit system and calorie is used in BTU system of units. For heat transferred, watt is the standard unit.
Answer to: If 1495 J of heat is needed to raise the temperature of a 365 g sample of a metal from 55.0 C to 66.0 C, what is the specific heat...
