Specific Heat Of Water At Room Temperature

The specific heat specific heat capacity at constant pressure and constant volume processes and the ratio of specific heats and individual gas constants r for some commonly used ideal gases are in the table below approximate values at 68 o f 20 o c and 14 7 psia 1 atm.

Specific heat of water at room temperature.

Water specific gravity figures and tables showing specific gravity of liquid water in the range of 32 to 700 f or 0 to 370 c using water density at four different temperatures as reference water specific heat online calculator figures and tables showing specific heat of liquid water at constant volume or constant pressure at. The following table of specific heat capacities gives the volumetric heat capacity as well as the specific heat capacity of some substances and engineering materials and when applicable the molar heat capacity. For example at a temperature of 25 c the specific heat capacity can vary with the temperature the heat required to raise the temperature of 1 kg of water by 1 k equivalent to 1 c is 4 179 6 joules meaning that the specific heat of water is 4 179 6 j kg 1 k 1. The specific heat capacity c p of liquid water at room temperature and pressure is approximately 4 2 j g c.

Specific heat of water vapor h 2 o at temperatures ranging 175 6000 k. For liquid at room temperature and pressure the value of specific heat capacity cp is approximately 4 2 j g c. This means it takes 4 2 joules of energy to raise 1 gram or 1 milliliter if you d rather think of the equivalent volume of 1 gram of water of water by 1 degree celsius. This value for cp is actually quite large.

Specific heat c is the amount of heat required to change the temperature of a mass unit of a substance by one degree. The specific heat is given at varying temperatures c and f and at water saturation pressure which. Water has a specific heat capacity of 4182 j kg c. The specific heat capacity of a substance is the quantity of heat energy required to raise the temperature of 1 kg of the substance by 1 c the symbol used for specific heat capacity is c and the units are j kg c or j kg k.

When calculating mass and volume flow in a water heating systems at higher temperature the specific heat should be corrected according the figures and tables below. Some typical values of specific heat capacity for the. Generally the most constant parameter is notably the volumetric heat capacity at least for solids which is notably around the value of 3 megajoule per cubic meter and kelvin. Specific heat of water.

Note that these units may also be written as j kg 1 c 1 or j kg 1 k 1. Water is one of the latter it has a high specific heat capacity because it requires more energy to raise the temperature. This implies that it takes 4 2 joules of energy to raise 1 gram of water by 1 degree celsius. For conversion of units use the specific heat online unit converter.
