One of the most important microscopic properties of gas molecules is velocity. there are several different ways to describe statistically the average velocity of a molecule in a gas. the most obvious measure is the average velocity v⃗ avg. however, since the molecules in a gas are moving in random directions, the average velocity is approximately zero. another measure of velocity is (v2)avg, the average squared velocity. since the square of velocity is always

Scout feels ill one day before school. her mother puts a thermometer in her mouth and the temperature begins to climb to 100°f. what is happening between the cooler thermometer and scout's body? a) scout's body is applying a force to the particles in the thermometer. b) kinetic energy is being transferred from her mouth to the thermometer. c) potential energy is being lost by the thermometer and gained by scout's body. d) the potential energy stored in foods is converted to mechanical energy to raise the mercury in the thermometer.
