The Difference of Temperatures Between Low-Emissivity Glass and Regular Glass

The purpose of this experiment was to investigate the difference between the amount of heat radiation absorbed through a regular glass pane and a sheet of low-emissivity glass. We constructed two insulated boxes and put the two types of glass on top of each box. Two heat lamps were placed above each sheet of glass. The initial and final temperatures inside the boxes were recorded from the thermometers. We performed a two-sample t test to compare the mean of the change in temperature for the regular glass trials and the means for low-emissivity glass trials. We calculated a tiny P-value of 4.52 x 10^-52 within a 95% confidence level. Because the value is so small we found that the low-emissivity glass had the lower change in temperatures which meant that it was more effective at block the radiation from the heat lamps. This is because the low-emissivity glass was created to not transmit as much heat into a home.
