Chapter Two, Lesson Three: Gas Behavior

Question 1

Charles’s law

Answer 1

When the temperature of a gas at constant pressure is increased, its volume increases. When the temperature of a gas at constant pressure is decreased, its volume decreases. This principle is called Charles’s law.

Question 2

directly proportional

Answer 2

When a graph of two variables is a straight line passing through the origin, the variables are said to be directly proportional to each other.

Question 3

Boyles’s law

Answer 3

When the pressure of a gas at constant temperature is increased, the volume of the gas decreases. When the pressure is decreased, the volume increases. This relationship between the pressure and the volume of a gas is called Boyles’s law.

Question 4

inversely proportional

Answer 4

When the product of two variables is constant, the variables are inversely proportional to each other.
