Determining The Specific Latent Heat Of Fusion For Ice Determining The Specific Latent Heat Of Vaporization For Water Latent Heat Latent heat of a substance is the amount of energy absorbed or released by the substance during a change in its physical state that occurs without changing its temperatu...
2) latent heat of vaporization 汽化潜热 1. Development of measurement system for saturated vapour pressure and calculating software for latent heat of vaporization; 饱和蒸汽压测量及汽化潜热推算系统的开发 2. Measurement of latent heat of vaporization of liquid nitrogen using computer data acquisition...
measure both the readings of the electric meter and the electric balance for several times (use a camera to record those if you want accuracy). Plot a graph about energy supplied to the heater against weight of the whole setup. As E=ml latent heat=E/m therefore latent heat is...

Define heat of vaporization What is thermal equilibrium? What is the study of heat? What is the temperature in space? What is the maximum temperature? What is latent heat of evaporation? What are the three types of heat transfer? Give an illustrative example for each type. What does the la...
In summary, specific heat capacity is the amount of heat energy required to raise the temperature of one unit mass of a substance by one degree Celsius. It differs from heat capacity in that it takes into account the mass of the substance. Factors such as molecular structure, density, and ...
