Specific Heat Of Water At Room Temperature

Some typical values of specific heat capacity for the.

Specific heat of water at room temperature.

Specific heat of water vapor h 2 o at temperatures ranging 175 6000 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. This value for cp is actually quite large. Water has a specific heat capacity of 4182 j kg c.

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 specific heat is given at varying temperatures c and f and at water saturation pressure which. Note that these units may also be written as j kg 1 c 1 or j kg 1 k 1. Because water is such an important and common substance we even have a special way to identify the amount of energy it takes to raise one gram of water by one degree.

This implies that it takes 4 2 joules of energy to raise 1 gram of water by 1 degree celsius. 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. 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. The specific heat c p and c v will vary with temperature.

Specific heat of water. Water is one of the latter it has a high specific heat capacity because it requires more energy to raise the temperature. 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. 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.

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. The specific heat capacity c p of liquid water at room temperature and pressure is approximately 4 2 j g c. 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.
