All the tools & learning materials you need for study success - in one app.
Get started for freeTwo containers hold several balls. Once a second, one of the balls is chosen at random and switched to the other container. After a long time has passed, you record the number of balls in each container every second. In , you find times when all the balls were in one container (either one) and the other container was empty.
a. How many balls are there?
b. What is the most likely number of balls to be found in one of the containers?
of a monatomic gas interacts thermally with of an elemental solid. The gas temperature decreases by at constant volume. What is the temperature change of the solid?
A room contains air at . What is the room's thermal energy?
A ball is at rest on the floor in a room of air at . Air is nitrogen and oxygen by volume.
a. What is the thermal energy of the air in the room?
b. What fraction of the thermal energy would have to be conveyed to the ball for it to be spontaneously launched to a height of ?
c. By how much would the air temperature have to decrease to launch the ball?
d. Your answer to part is so small as to be unnoticeable, yet this event never happens. Why not?
is a typical walking speed. At what temperature would nitrogen molecules have an speed of ?
