Thermodynamics - Lab Report ExampleIt is a common observation that when a hot dust is brought in contact with a low temperature body, wobble of conflagrate takes quad from the hot body to the cold body. If two the bodies are identical in material and dimension and the entire system is thermally insulated whence it can be found that both the bodies achieve same temperature indicating that the transfer of heat takes place until both the bodies are in the state of thermal equilibrium. This process of heat transfer is known as heat conduction.Conduction in the language of physics can be explained by the phenomenon of transfer of kinetic efficacy (heat) by interaction between the vibrating particles (lattices) or movement of free electrons in a body.In this experiment, additive heat conduction in an insulated long slender brass bar as shown in image 1 is examined. We assume the brass bar to be of length L, a high temperature is kept ageless at one end, and a low temperature on the other. The reason for thermally insulating the brass bar circumferentially is to encounter that heat conduction takes place linearly along the axis of the bar. The equation governing the heat transfer is known as Fouriers right, and can be is written asThe thermal conductivity is a extend of temperature, but it can be treated as a constant over small temperature ranges. The thermal conductivity of a material is dependent on the material and it varies with direction, structure, humidity, pressure and temperature change. The transfer of energy takes place in solids by two methodsWe will study Fouriers Law through this experiment by conclusion the thermal conductivity for brass and comparing this value to the real actual value from one compose experiment. To do this we will calculate the cross sectional area of the bar and the gradient slope from a plot of measured temperatures vs. length. We can then use these values in an arranged version of Fouriers Law to find the thermal conductivity by the following relationThe experimental
