Question

Chapter 13, Problem 1OQ

To determine

With relation to the air outside the balloon, the effect on the temperature, pressure and density of the air inside the balloon when it is heated by a flame

Expert Solution & Answer

Answer to Problem 1OQ

Solution:

Temperature is higher inside the balloon
Pressure is same inside and outside balloon
Density is lower

Explanation of Solution

A. Temperature is higher inside the balloon. This is the basic principle on which a hot-air balloon works. As the air inside the balloon gets heated by the flame, it rises upwards through the surrounding air, which is colder.

B. Pressure is the same inside and outside the balloon. Otherwise, the balloon would inflate or deflate. The density of air particles is lower because of the high temperature inside the balloon. This should lower the pressure. But because of the higher energy of these particles, they are moving faster and even this smaller quantity ends up exerting the pressure required to balance the outside pressure.

C. Density is lower. Because of the higher temperature of the air, the density is lower.

Imagine you are out for a stroll on a sunny day when you encounter a lake. Unpolarized light from the sun is reflected off the lake into your eyes. However, you notice when you put on your vertically polarized sunglasses, the light reflected off the lake no longer reaches your eyes. What is the angle between the unpolarized light and the surface of the water, in degrees, measured from the horizontal? You may assume the index of refraction of air is nair=1 and the index of refraction of water is nwater=1.33 . Round your answer to three significant figures. Just enter the number, nothing else.
