Latent Heat Of Fusion Chart. Jozsefgaraifiuedu Abstract The induced atomic movement at melting has to overcome on a viscous drag resistance. The heat of fusion is the quantity of heat necessary to change 1 g of a solid to a liquid with no temperature change Weast 1964 p. Latent heat of fusion is the heat consumed or discharged when matter melts changing stage from solid to fluid-structure at a consistent temperature. The latent heat of fusion of a substance is the amount of heat required to convert a unit mass of the solid into liquid without change in temperature The latent heat of melting for some common solids are indicated below.
This video shows how the temperature of ice remains at 0C while melting. 10 points Using the data above and the supplementary sheet calculate the latent heat of fusion for each trial and enter values in the chart above. This should be written as if you were instructing someone who was not familiar with this lab. The latent heat of fusion of a substance is the amount of heat required to convert a unit mass of the solid into liquid without change in temperature The latent heat of melting for some common solids are indicated below. The heat of fusion for ice or water is L f 333 x 10 5 Jkg. Oil Palm 35.
Latent heat of fusion also known as enthalpy of fusion is the amount of energy that must be supplied to a solid substance typically in the form of heat in order to trigger a change in its physical state and convert it into a liquid when the pressure of the environment is kept constant.
It needs heat energy to melt and so it takes this heat from its surroundings ie. This video shows how the temperature of ice remains at 0C while melting. It is also a latent heat and is sometimes called the latent heat of fusion. The formula for heat absorbed or liberated by a substance during the change of state. The specific heat of frozen ice is ci 2090 Jkg Co. The specific heat of liquid water is cw 4186 Jkg Co.
