The Thermal Coefficient of Linear Expansion Date Due: 1/18/17 Name: Christopher Weeks Lab Partners : Everyone
Introduction: Different substances require different amounts of heat to produce a given temperature change. For example, the sand on a beach takes less time and energy to heat up compared to the water of the ocean. This behavior is characterized by the specific heat of a material, the amount of heat energy necessary to raise the temperature of a unit of mass of a substance by one unit of temperature. Objectives: 1 Tell what is meant by specific heat of a substance and compare the effects of different specific heats. 2 Calculate the heat necessary to raise the temperature of a given mass of a substance a particular number of degrees 3 Describe and explain how the thermal coefficient of linear expansion is measured Variables: T Temperature C L Length meters Aluminum
