Title: Specific Heat Capacities of Metals Experiment Date: 3/28/2012 Report Date: 4/4/2012 Purpose: The purpose of the lab is to measure the specific heat capacities of aluminum‚ steel and brass. Theory: The amount of heat (ΔQ) required to change the temperature of an object is proportional to the mass (m) of the object and the temperature change (ΔT) of the object. ΔQ= cmΔT where c is called as the specific heat capacity of the material. In the calorie units system the unit of quantity

Aim: i) To find the relationship between supplied energy and change in temperature of water. ii) To find the specific heat capacity (SHC) of water. Hypothesis: As time increases so does the temperature since the water is exposed to the heated wire for a longer period of time. Variables: The Dependent Variable is the temperature of the water‚ and since the Energy is calculated using temperature it is a dependent variable as well. The constant variables are the voltage and current. Theory:

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

Physics 1003 Experiment Report In this experiment‚ the technician began with the demonstration of solar energy. Solar energy is the conversion of light energy to electrical energy by using solar panels. Solar panels are devices that contained solar module which use light energy from light to generate electricity through the photovoltaic effect. And photovoltaic modules generate electricity from a frequency of light. From my observation of the experiment‚ I found that the panel is black in
