Question
Describing the invisible properties of gas (Kinetic Molecular Theory) rue or False: 1) Gases are composed of small particles 2) Gas molecules are usually close together 3) Gas molecules move rapidly because they are strongly attracted -4) There is a lot of empty space between the gas particles compared to the size of the particles. -5) As you increase temperature, you increase the average energy of the gas particles. The ABC's of Gas Fill in the blanks by writing (increases) or D (decreases) for a gas in a closed container. Pressure Vol ume Moles Temperature 6) 7) increases cons 8) constant decreases 9) 10) constant increases constant constant tant constant constant constant constant increases constant decreases constant increases constant 12) Which sample of a gas has the lowest pressure? Assume that all of the particles are identical and that the three samples are at the same temperature. fa) tb) to 4c)Explanation / Answer
1- A gas is composed of very small particles - this statement is true because gas occupied much more volume but there is lot of space between them.
2) There is very little empty space in a gas. This statement is true as explain in (1).
3) Gas particles move rapidly. There is lot of space and there is no force acting on gas particles hence they move rapidally . Hence this is true.
4) Gas particles do not attract or repel one another.this statement is true as explain in (3).
5) Gas particles move faster when the temperature increases. This statement is true. Because kinetic energy of gas particles increases when temperature increases.
