    Thermal Expansion

    • 644 Words
    • 3 Pages

    Thermal expansion is the tendency of matter to change in volume in response to a change intemperature.[1] All materials have this tendency. When a substance is heated‚ its particles begin moving more and thus usually maintain a greater average separation. Materials which contract with increasing temperature are rare; this effect is limited in size‚ and only occurs within limited temperature ranges. The degree of expansion divided by the change in temperature is called the material’s coefficient

    Thermal Expansion Thermal expansion is the tendency of matter to change in volume in response to a change in temperature‚ through heat transfer. The coefficient of thermal expansion describes how the size of an object changes with a change in temperature. Specifically‚ it measures the fractional change in size per degree change in temperature at a constant pressure. Several types of coefficients have been developed: volumetric‚ area‚ and linear. This is used depending on the particular application

    Experiment 1: Thermal Linear Expansion Abstract: The thermal linear expansion of copper and aluminum is the focus of this experiment where the two metals have a tendency to expand their length in response to the change of temperature. Each metals have their own coefficient of linear expansion which describes how the size of an object changes with a change in temperature while the pressure is held constant. We ’re able to determine the theoretical coefficient of linear expansion of the two metals

    Purpose: In this lab‚ we will heat up a metal rod and measure how much it expands. We will calculate its Coefficient of Linear Expansion‚ α‚ and prove the formula for thermal expansion‚ ΔL = αLiΔT. Also‚ we heat up a known volume of methyl alcohol and calculate its Coefficient of Volume Expansion‚ β‚ and prove the formula for volume expansion of a liquid ΔV = βViΔT. Equipment: Hollow Metal Rods of different metals‚ Steam Generator‚ Stand‚ Burner‚ Flexible Hoses‚ Motion Amplifier‚ Micrometer

    Page 1 of 4 Expansion Devices I. Introduction Expansion devices are basic components of a refrigeration system which carry out two major purposes: (1) the pressure reduction from the condenser to evaporator pressure and (2) the regulation of refrigerant flow into the evaporator. These expansion devices can be generally classified into two types which are namely the fixed opening type (flow area is fixed) and the variable opening type (flow area changes correspondingly with a change in mass

    Experimental Report Aim The objective of the laboratory report was to determine the thermal expansion coefficient of copper and other materials by measuring the relative change in length of bars of the materials as a function of temperature. Introduction The average coefficient of thermal expansion α over a temperature interval ΔT is given by ΔL / L0 = ΔT Where L0 is the length at some initial temperature‚ and ΔL is the change in length corresponding to a change in temperature

    PHYSICS FORM: 4D & 4E TOPIC: THERMAL PHYSICS Temperature determines the direction of net heat flow. It is the property o f an object. It’s the amount of kinetic energy a body possesses. Example Brass rod made hot at one end by placing it in a Bunsen flame‚ while other end is kept away at room temperature‚ there is a net transfer of energy from the high temperature region to the low temperature end.
