Abstract The objective of this lab was to determine the convective heat transfer coefficient of a heated sphere in an quiescent environment. In the experiment a hot brass sphere was put into water and cooled. The temperature of the sphere was recorded over a time of 600 seconds to see how it cooled and given temperature was recorded every 20 seconds. Results were then calculated at both of the time values 300 and 600 seconds. For the experimental results at time 300 seconds‚ the Rayleigh number

you’re thinking apes becoming humans you’re already wrong. There’s even evidence of evolution like fossils‚ DNA samples‚ similarities in bone structure‚ and even vestigial organs. The purpose of this lab is to see how evolution works and whether it is a reliable theory. Hypothesis: If there are 11 skulls that all have different structures 4 of them will be bipedal. Independent variable: Is all the measurements of each skull Dependent
