At temperature t the heat content of water vapour is: h w = 2501 + 1.84t Notice that water vapour, once generated, also requires more heat than dry air to raise its temperature further: 1.84 kJ/kg.C against about 1 kJ/kg.C for dry air. The enthalpy of moist air, in kJ/kg, is therefore: h = (1.007*t - 0.026) + g*(2501 + 1.84*t)

The calculators use the specific heat capacity of water of 4186 J/kg/°C (Joules per kilogram per degree Celsius). The heat capacity is largely constant in the temperature range that the calculators work (34-210°F or 1-99°C). It is the way it is taught at school. For practical purposes, it should be precise enough.
Specific heat calculator converts joule per kilogram, kilojoule per kilogram, calorie per gram, Btu per pound, pound per horsepower to vice versa with metric conversion.

All we need to know to compute the latent heat is the amount of substance and its specific latent heat. The formula is: Q = m * L, where. m [kg] is the mass of the body, L [kJ/kg] is the specific latent heat, Q [kJ] is the heat absorbed or released depending on the direction of the transition.
Specific Heat DIRECTIONS: Use q = (m)(AT)(Cp) to solve the following problems. Show all work and units. 1. A 15.75-g piece of iron absorbs 1086.75 joules of heat energy, and its temperature changes from 250C to 1750C. Jul 02, 2020 · Specific heat tells you the amount of energy needed to raise each unit one degree. For example, it takes .417 Joules to raise 1 gram of water 1 degree Celsius. So, water's specific heat is .417 J/C per gram. The specific heat of a material is constant. That means that all pure water has the same specific heat-- .417 J/C.
