kea.kar.nic.inIf the mass of the substance is unity then the heat capacity is called Specific heat capacity. OR the specific heat. Q = C m ∆t Where Q Æ quantity of heat absorbed by a body m Æ mass of the body C Æ Specific heat capacity of a substance it depends on the nature of the material of the substance. S.I unit of specific heat J kg-1 K-1 NOTE ...

Experiment 9 Specific Heat Capacities of Metals
www2.chem21labs.comThe amount of heat released or gained by an object (q) depends on the mass of the object (m) and the change in temperature of the object (∆T ). q = mC s∆T (9.1) In this equation, the proportionality constant C s is called the specific heat capacity and every substance has a characteristic value. For example, the specific heat capacity of water
CHAPTER 7 DRYING - NZIFST
www.nzifst.org.nzweight of the original material, for drying under atmospheric pressure. The latent heat of vaporization of water at 100oC and at standard atmospheric pressure is 2257kJkg-1. The specific heat capacity of the food is 3.8 kJkg-1oC 1 and of water is 4.186 kJkg-1oC . Find also the energy requirement/kg water removed. Calculating for 1 kg food
Interpreting DSC Data - UC Santa Barbara
www.mrl.ucsb.eduA DSC event peak typically contains the following components: • Baseline: This is the expected signal (or change in signal) if no transition event occurs (e.g. if the enthalpy change of melting or H fusion were zero). This is not always a flat line, as the specific heat capacity of a material is not guaranteed to be constant as temperature ...
