<span>Closing ratio is the number of deals you close compared to the number of presentations ( or calls ) you make. In this case it means: 1 sale : 3.5 calls ( average ). We will use proportions: 1 : 3.5 = 23 : x. x = 23 * 3.5, x = 80.5. We have to round this number upwards to be more certain that you get the 23 sales. Answer: 81 calls </span>
<span>Answer: option a. It is the only valid option because when molecules gain speed they increase their kinetic energy and the processes described in options b, c, and d imply decrease in internal energy, then you can discard them. Regarding, the valid option, a., when the molecules with higher speed will increase their chances to get out of the liquid phase passing to gas state. </span>
