Chapter 17: Problem 5

Suppose you start running while holding a closed jar of air. Do you change the average speed of the air molecules? The average velocity? The temperature?

Short Answer

Expert verified
No change in the average speed of air molecules and temperature. Only the average velocity changes.

Step by step solution

01

Understanding the Concept of Average Speed

The average speed of the air molecules in the jar doesn't change because it doesn't depend on the motion of its containing jar. The speed of a gas' molecules depends only on its temperature, under normal conditions.
02

Understanding the Concept of Average Velocity

The velocity indeed changes. Average velocity is speed plus direction, and as the jar changes its position while you are running, the average direction of the molecules' paths is changed, and hence changing the average velocity. Yet, the speed of each individual molecule relative to the jar remains unchanged.
03

Understanding the Concept Temperature

Temperature of the gas does not change. Temperature is directly related to the kinetic energy of the molecules, which is not affected by the overall motion of the container.

Which takes more heat: melting a gram of ice already at \(0^{\circ} \mathrm{C},\) or bringing the melted water to the boiling point?

A \(50-\mathrm{g}\) ice cube at \(-10^{\circ} \mathrm{C}\) is placed in an equal mass of water. What must the initial water temperature be if the final mixture still contains equal amounts of ice and water?

The triple point of water defines a precise temperature, but the freezing point doesn't. Why the difference?

A helium balloon occupies \(8.0 \mathrm{L}\) at \(20^{\circ} \mathrm{C}\) and 1.0 -atm pressure. The balloon rises to an altitude where the air pressure is 0.65 atm and the temperature is \(-10^{\circ} \mathrm{C}\). What's its volume when it reaches equilibrium at the new altitude?
