In thermodynamics, the Van der Waal's equation relates the mean pressure, p, of a substance to its molar volume v at some temperature T as follows: when p = 5.2 and v = 2.9? Chemists are interested in the curves, called isotherms, described by this equation when the temperature is held fixed, and R is a constant.

Susan is a volunteer at the SPCA and has a 2-hour shift per day. Occasionally she assists the vet with health checks. She also handles a few admin duties. The vet is open 6 days a week. Monday to Saturday from 08:30 to 16:30. 4.1Calculate Susan’s total volunteer hours per week. 4.2A dog’s normal temperature is between 101,5˚F to 102,5˚F. If a dog has a temperature of 38,8˚C, will it fall in the normal temperature range or is the dog feverish? Use the formula ˚F= (˚C x 1,8) + 32 to confirm your answer. 4.3The vet’s weight is 67,76 kg. While holding the dog in her arms their weight is 89240g.Determine the weight of the dog to the nearest kilogram.

You put n = 20 rats in a cage that is in a room with a 65-degree temperature. The next day you put them in a cage with a 70-degree temperature. On the final day of the study you put them in a cage with a 75-degree temperature. For each of the three days, you measure how many minutes of each hour they spent running on their exercise wheel. To compare the time they spent running on the wheel between the three different days (in other words, between the three different temperatures of 65, 70, and 75 degrees), what kind of hypothesis test should you do?
