# Latent fusion of ice lab report

The latent heat of fusion (associated with the melting of a solid) is defined by: l f = heat required to melt 1g of solid thus, to melt a mass m of ice it takes an amount of energy q = ml f. The latent heat of fusion of a substance is the energy involved in changing the state of unit mass of the substance at the melting/freezing point the latent heat of vaporization of a substance is the energy involved in changing the state of unit mass of the substance at the boiling point. Fusionofice7969cal15osimilarlyfordieterici'sdata7960cal15° a summary of theforegoingvaluesgivingthe results of the most important determinations subsequent to 1870 is given in table 2.

Best answer: sources of error: 1) inaccuracy in reading balance 2) inaccuracy in reading thermometer 3) ice cube not dried off completely 4) water spilled or evaporated 5) water should cool the same amount below room temperaure as the warm water was initially warmed above room temperature 6) not all of ice. Phys 1400: physical science laboratory manual lab 05: latent heat page 01 i of the ice: 3 calculate the latent heat of fusion l for each of the three trials you performed assume that the energy lost by the warm water is gained by the ice, but notice that the energy is used ﬁrst to melt the ice, then to raise the temperature of the. Latent heat of fusion of ice report in a table the values of the water equivalent, the three experimental values of the latent heat of fusion, the average of these values, the book value, and.

Latent heat of fusion goal: to measure the latent heat of fusion for water lab preparation in this lab you will mix some ice and water and allow them to come to thermal equilibrium, thus review of calorimetry problems that include phase changes is. Latent heat of vaporization is 75 times as large as the latent heat of fusion ie the energy required to melt something is considerably lower than the energy required to vaporize something this is the reason why a burn caused by steam at 100 0 c will be a lot more severe than a burn caused by water at 100 0 c. In this experiment you will find the latent heat of fusion of ice when ice at 0°c is mixed with warm water at some temperature, t i , the water will cool to a final temperature, t f. From this equation you can calculate the specific latent heat of fusion of ice the accepted value is 334,000 j/kg try to explain why your experiment gave a different answer. 7/16/12 heat of fusion heat of fusion for ice introduction: this lab report is a step by step process in calculating the heat of fusion for ice and to compare the differences between salt added to room temperature water and salt added to icy water.

Find the latent heat of fusion, lf, according to lf = q ÷ m by dividing the heat, q, absorbed by the ice, as determined in step 3, by the mass of ice, m, determined in step 4 in this case, lf = q / m = 2293 j ÷ 70 g = 328 j/g. Chapter 3 calorimetry - speciﬁc heat and latent heat name: lab partner: section: 31 purpose the purpose of this experiment is to study the relationship between heat and tempera-ture calorimetry will be used to investigate speciﬁc heats of materials and the latent heat 332 latent heat of fusion for ice • fill the cup about 1 3 full. The purpose of this lab is to determine the latent heat of fusion of ice in this the result will be an experimental value of the latent heat of fusion that is too low lab report discuss the various errors and how they impacted your experimental results you may use the back of this lab handout.

## Latent fusion of ice lab report

Latent heat of fusion abstract latent heat of fusion (lf) is the heat energy absorbed of the substance as it changes its state from the solid state to the liquid state without the change in temperature this is expressed in joules (j) per unit mass (kg) of the substance in this experiment, our goal. The latent heat of fusion of ice a small amount of ice is placed in a calorimeter containing water by knowing the masses of the ice, the water, and the calorimeter, and the resulting temperature change after the ice melts, the latent heat of fusion of ice is found. Tap 608- 2: the latent heat of fusion of ice this experiment is designed to measure the amount of heat needed to turn 1 kg of ice at 0 oc into 1 kg of water at 0 oc you will need.
