Title: Specific Heat of Solids II. Object: To determine the specific heat capacity of solids by methods of mixtures. III. Theory: When to or more substances at different temperatures are mixed‚ heat will flow from the substance of higher temperature to the substance of lower temperature. The heat flow will continue until equilibrium in temperature is reached. From the Law of Conservation of Energy‚ whatever amount of heat is lost by the hot substance must be equal to the heat gained by the cold

6 report Anita Dey Thursday 8am Abstract: We recently performed a liquid nitrogen experiment in finding the Latent heat of the substance. We isolated two parts of the experiment in order to find out how much evaporation of the liquid nitrogen was from the surroundings B and how much evaporation from the electricity G. 1. When a substance is undergoing a phase transition‚ more heat (energy) is being added to the Substance but its temperature (a way of measuring its energy) is not changing. Where

State Heat Transfer laboratory were to study the rates of heat transfer for different materials of varying sizes‚ to develop an understanding of the concepts of forced and free convection and to determine the heat transfer coefficients for several rods. These objectives were met by heating several rods and allowing them to cool through free convection in air‚ free convection in water and forced convection in water- while monitoring their change in temperature over change in time. Seven heat transfer

Forced Convection Heat Transfer I. Introduction This laboratory deals with forced convection‚ forced convection can be considered as a staple of heat transfer. That is to say that forced convection can be found in almost any heat transfer problem‚ and thus understanding its importance and how it affects a given problem is one of the more important learning objectives/outcomes of heat transfer. When dealing with forced convection the most important section‚ after understanding how convection

HEAT ENGINE WORKING CYCLES An engine is a device which transforms one form of energy into another form. However‚ while transforming energy from one form to another form‚ the efficiency of conversion plays an important role. Normally‚ most of the engines convert thermal energy to mechanical work and therefore they are called ‘heat engines’. Heat engine is a device which transforms the chemical energy of a fuel into thermal energy and utilizes this thermal energy to perform useful work. Depending

3 Methods of Heat Transfer Now in Physics we learn that there are three methods of heat transfer‚ this being: Radiation‚ Conduction‚ and Convection. Let’s start with radiation; radiation is the transfer of energy as electromagnetic waves. So basically it does not need to directly touch anything or move any particles around‚ much like convection and conduction do. Radiation mostly occurs through empty space‚ so I think a good example of radiation would be when you feel warm in front of a fire
