A C), and the specific … heat of water is 4180J/(kg. Thus the heat of vaporization is the amount of heat that we need to turn one gram of a liquid into a vapor, without any rise in the temperature of the liquid. Resistivity is a measure of the resistance of a given size of a specific material to electrical conduction. The calorie is a unit of heat and it equals 4.2 J where 1 J = 1 kg m²/s².Suppose we employ a system of units in which unit of mass is α kg , unit of length is βm,unit of time γs.What will be the magnitude of calorie in the new system? The heat of vaporization of water is the highest known value. This site is using cookies under cookie policy. Unit of heat: Because heat is a form of energy, its units are those of energy, namely, the joule (J) in the SI system.
