This worked example problem demonstrates how to calculate the specific heat of a substance when given the amount of energy used to change the substance's temperature first, let's review what specific heat is and what equation you use to find it specific heat is defined as the amount of heat per. Heat lost by water is equal to the mass times the specific latent heat of fusion and the equation is vti=ml, m is mass of water in difference, t stands for the time taken for heat the ice and l is the latent heat of fusion of ice. Latent heat of ice and steam are given as 80 cal/g and 540 cal/g respectively solution: if the full steam is converted into the water at 100∘c, then the temperature of water falls from 100 ∘ c to 10 ∘ c and then a part of water at 0 ∘ c is turned into ice.

Specific latent heat q - specific latent heat introduction value for the specific latent heat of fusion of water: specific latent heat is where the amount of energy (in joules) needed to change the state of 1kg of a substance is called its specific latent of heat. An example of a high specific heat is water’s specific heat, which requires 4184 joules of heat to increase the temperature of 1 gram of water 1 degree celsius scientifically, water’s specific heat is written as: 1 calorie/gm °c = 4186 j/gm °c. Sameera raziuddin latent heat of fusion april 11, 2011 abstract: a calorimeter, water at room temperature, ice, and a pasco gls explorer were used in combination with a known value of the latent heat of fusion to create and carry out an experiment to determine the mass of an unknown amount of ice. Water has a high latent heat of vaporisation which means a lot of energy is required to evaporate it when it evaporates, water draws thermal energy out of the surface it’s on, which can be observed in sweating below is an example essay on the importance of water for example its very high specific heat capacity, 42kj/g.

Latent heat is the heat energy per mass unit required for a phase change to occur if we think about substances at a molecular level, gaseous molecules have more vibration than liquid molecules. The heat released by the boiling water is the product of specific heat, mass, and temperature change, while the heat required to melt the ice is the product of the mass of ice and the latent heat (1) einitial = mwatercpwater (tw) + micecpice (tice) (2) efinal = mwatercpwater (tw) + micecpice (tice) + micelice, where m is defined as mass, cp is.

Water for example has a specific heat of 1 cal/g/ o c in general, the gain in heat is accompanied by either a change in volume or a change in pressure (eg the water in the pot swells somewhat as you heat it if you heat gas in a fixed volume, its pressure goes up. The specific latent heat of fusion measures the amount of heat energy required to change 1 kg of a solid into a liquid in this lab experiment, ice was added to pre-weighed, room temperature water in a calorimeter. From the calculations the specific latent heat of vaporization of water is calculated to be 2500 j/g ±60 j/g the literature value of specific latent heat of vaporization of water is 2260 j/g, which is quite low we will write a custom essay sample on latent heat of vaporization of water for you for only $1390/page order now.

The stages of the refrigeration cycle engineering essay print reference this disclaimer: so there is always some form of energy flowing as heat into a specific sample at a rate that is proportional to the temperature difference latent heat describes the amount of energy in the form of heat that is required for a material to undergo. This specific latent heat quantifies the transfer of energy when a substance's state changes from a solid to a liquid or from a liquid to a solid two formulas has be derived from this property: example \(\pageindex{5}\) the specific latent heat of sulfur is 484 kj/kg and the quantity of heat is 0706 kj/. Essays on heat death of the universe new topic specific latent heat on the nature of the universe black death some researchers are searching for an explanation that encompasses both dark matter and dark energy one example of such a theory uses a form of energy called a scalar field (it is a field because it has magnitude, energy and.

- The new topic specific latent heat is one of the most popular assignments among students' documents if you are stuck with writing or missing ideas, scroll down and find inspiration in the best samples new topic specific latent heat is quite a rare and popular topic for writing an essay, but it certainly is in our database.
- The sample elements used were five different metals, aluminum (al), lead (pb), copper (cu), and two of which that are unknown, expected to be explained by comparing the experimental specific heat capacity (cp) against the accepted cp of a the metal my observations lead to test.

The latent heat of vaporization of water the latent heat of vaporization of water aim: the aim is to determine the latent heat of vaporization of water by doing an experiment of boiling water theory: the latent heat of vaporization is the amount of energy that is required to transfer a kg of liquid from the liquid state to the gaseous state. The specific heat is the amount of heat per unit mass required to raise the temperature by one degree celsius an example: the specific heat of water is 1 calorie/gram °c = 4186 joules/gram °c which is higher than any other common substance. In other words, the sum of the latent heat of fusion, shapes change plus the thermal energy for changing the temperature of the melted ice, quaternaries change, is the same as the herbal energy for changing the temperature of the warm water.
