When the average kinetic energy of the molecules goes up (a rise in temperature), the average speed of the molecules increases. And lower average kinetic energy of the molecules means they have lower speed. However, a change in average kinetic energy is not directly proportional to a change in average speed.

In the United States, paid vacation is typically two weeks or less per year for the first few years of employment in addition to roughly 10 paid federal holidays. Generally PTO hours cover everything from planned vacations to sick days, and are becoming more prevalent in the field of human resource management.Unlike more traditional leave plans, PTO plans don't distinguish employee absences from personal days, vacation days, or sick days. If PTO hours go unused, employees may sometimes call in sick near the end of the year so they can obtain the benefit of paid leave before it disappears. 2  Employers may counter this tendency by paying employees for some or all of their unused days at year-end or upon retirement or resignation.
