the specific latent heat of fusion of water? Specific latent heat of fusion is the amount of heat absorbed or released by a substance when changing states. This could be boiling or melting. Latent heat of fusion is the amount of energy needed to melt a substance‚ while latent heat of vaporisation is the amount of energy needed to boil a substance. The specific latent heat of fusion of water is 334 j/g In the graph‚ you can see that as the temperature increases more energy is needed to heat the

Latent heat is a science term used to describe the amount of energy that has been absorbed or released when a substance goes through the process of changing states. | Latent Heat of Fusion - heat absorbed by a unit mass of a solid at its melting point in order to convert the solid into a liquid at the same temperature The heat absorbed as a substance changes phase from liquid to solid‚ a process called fusion or solidification. For water‚ Latent Heat of Solidification - heat liberated

specific heat of solids 1. Introduction Heat capacity of a body is the quantity of heat required to raise the temperature of the body by 1oC. The specific heat of a substance is the heat capacity per unit mass. Thus‚ heat capacity = mass x specific heat. The specific heat is essentially a measure of how thermally insensitive a substance is to the addition of energy. Heat and temperature are really different quantities. Heat is a quantity of thermal energy‚ while temperature determines the

Experiment I: Thermochemistry Background: Thermochemistry is the branch of chemistry that focuses on the studies of chemical reactions or physical changes and heat associated with chemical reactions. According to the first law of thermodynamics‚ energy cannot be created or destroyed but it can be converted from one form into another and/or transferred between different atoms‚ molecules‚ or substances. In general‚ energy can be classified into two categories: kinetic and potential. Kinetic energy

the experiment aimed to determine the specific heat of two different metals‚ Lead and Zinc‚ in order to calculate their individual atomic weight. Theory The calorimeter consists of a metal outer cup‚ a removable metal inner cup‚ which is held in place by a rubber ring‚ and an insulating lid with a small opening for a thermometer. It is a closed system as the air between the inner cup and outer cup insulates the water and heated metal‚ so‚ ideally‚ all heat is contained within the calorimeter (1)

g_housesrev3.shtml The specific latent heat of a substance is a measure of how much heat energy is needed to melt or boil it. It is the energy needed to melt or boil 1 kg of the substance. Different substances have different specific latent heats. The specific latent heat of a given substance is different for boiling than it is for melting. The table shows some examples. Latent heats of substances substance specific latent heat of melting kJ/kg specific latent heat of boiling kJ/kg water

Identification of the Specific Heat Capacity for a Calorimeter and of the Enthalpy of an Acid-Base Reaction Abstract The purpose of this lab was to first‚ determine the specific heat capacity of a homemade calorimeter‚ and second‚ to calculate the enthalpy of reaction for an acid-base reaction between 6M KOH and 6M HNO3. To determine the specific heat capacity of the calorimeter‚ two differing temperatures of water were measured and volume was measured and mixed within the calorimeter. The

into the specific heat capacity of a solid Introduction: In this experiment I investigated the specific heat capacity of brass and aluminium‚ in order to do this I arranged a series circuit with a heater‚ the heater would go inside the brass and aluminium and heat it for an amount of time in which I decided‚ I also used the voltmeter in parallel. This arrangement made me able to arrange the equation VIT= mcΔθ‚ since the electrical energy in would be equal to the mass times the specific heat capacity
