Title & Abstract

Measurement of pressure at zero kelvin

Our project aims to find out about what the pressure is at zero kelvin. Our hypothesis is: If the pressure is zero, then the temperature is -273.15ÂșC. We did this by using a datalogger with a temperature sensor, TCA-BTA, and a pressure sensor.We measured the temperature and pressure at different temperatures and used this app called LOGGER PRO 3 to draw the approximate graph with temperature as the independent variable and pressure as the dependant variable.The results we got were unexpecting as we expected a very inaccurate experiment.We got a graph quite near the to the real answer.Our results had a error of 1.76%.We got a graph for -273.1444 degrees celsius.0.00556 degrees
