12. Learning Objectives Solve problems involving Charles’ Law using the mathematical formula V 1 /T 1 =V 2 /T 2 Appreciate the importance of gas laws in everyday life and scientific advancements Explain the relationship between the volume and temperature of a gas, as described by Charles’ Law

13. UNLOCKING OF TERMS 1. Charles’s Law - is an experimental gas law that describes how gases tend to expand when heated. 2. Volume - the amount of space that a substance or object takes up 3. Temperature - the average kinetic energy of a substance's molecules or atoms. 4. Gases - a state of matter where the molecules or atoms are spread out and move freely.

14. KEY CONCEPTS Charles’ law, also known as the ‘Law of Volumes’ is an experimental gas law that explains how gases tend to expand when exposed to high temperature. Charles’ Law is an ideal gas law wherein the volume of an ideal gas is directly proportional to the absolute temperature at constant pressure. This law states that the volume of a given amount of gas at constant pressure varies directly with Kelvin temperature.

15. According to Charles’ law, when the pressure of a gas is held constant, and there is an increase in its temperature, its volume also increases. Every time we heat a sample of gas, its particles become more active and energetic so they move rapidly which causes them to spread out because the volume of the gas is increased as expected.

20. JACQUES CHARLES Jacques Charles, a French physicist, discovered Charles' law in the 1780s.

21. What is Charles’ Law? Charles's law, a statement that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant.

22. Charles’ Law Equation: In Boyle’s Law, the temperature is constant. However, in Charles’ Law our constant is the pressure.

23. Note : to Convert degree Celsius to Kelvin, use this formula: K=C + 273.15.
