An experiment is designed to determine if the amount of sugar in a drink affects the likelihood that bees will be attracted to it. sample a is 100 ml of pure water. sample b is 100 ml of water with 1 gram of sugar dissolved in it. sample c is 100 ml of water with 2 grams of sugar dissolved in it. all samples are placed on a picnic table. one observer is assigned to each drink. the observers count the number of bees that visit the drink during a 15-minute interval. which of the following is the best hypothesis for this experiment?

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
