Specific and Latent Heat Calculations As heat is added to a substance an increase in temperature followed by a change in state may be observed. When water is used to take heat from a fire, normally both a change of temperature and a change of state occur. Note that for a system in thermal equilibrium if ice and water are present the temperature must be 0 0 C. If heat is added, ALL the ice must melt before the temperature will rise above 0 0 C. There is this farmer who is having problems with his chickens. Specific heat definition is - the heat in calories required to raise the temperature of one gram of a substance one degree Celsius. the heat in calories required to raise the temperature of one gram of a substance one degree Celsius… Similarly, when liquid water evaporates, the system must provide enthalpy to the vapor by cooling.

The latent heats of vaporization, fusion, and sublimation of water at 0°C are, respectively, Water absorbs heat slowly and releases heat when there is less sun. This helps counter drastic shifts in temperature, which would be devastating to life. By comparison, if the world were made of mostly ethanol, the temperature would fluctuate rapidly because ethanol has a much lower heat of vaporization and specific heat. Given that the specific latent heat of fusion of ice is 3.4 x 10 5 J/kg, calculate the average rate at which the contents gain heat from the surroundings.

STANDARD THERMODYNAMIC PROPERTIES OF CHEMICAL SUBSTANCES This table gives the standard state chemical thermodynamic properties of about 2400 individual substances in the crystalline, l iquid, and gaseous states. Specific heat of a solid substance can be determined by the "Method of Mixture" using the concept of the "law of Heat Exchange" i.e. heat lost by hot body = heat gained by cold body The method of mixture based on the fact that when a hot substance is mixed with a cold substance, the hot body loses heat and the cold body absorbs heat until thermal equilibrium is attained. Latent heat is associated with processes other than changes among the solid, liquid, and vapour phases of a single substance. Many solids exist in different crystalline modifications, and the transitions between these generally involve absorption or evolution of latent heat.
