Matter
Gas
It is the measure of hotness or coldness of a substance.
Temperature
Huge amounts of gases like body sprays can be placed in a small aerosol spray can because gases can be ________.
Compressed
Softdrink is a wonderful application of gases. What gas gives the acidic taste and the fizz when the bottle or can is shaken.
Carbon dioxide
A change in matter that results in the formation of a new substance that has its own properties.
Chemical change
The amount of space occupied by gases.
Volume
Balloons float while the ocean or the buildings do not. This is because gases aren't tightly packed. What characteristic of gases is described?
Density
When you were in grade 9, you studies about the respiratory system. What are the two properties of gases that enables us to breathe.
Pressure and Volume
The energy in motion or movement of particles
Kinetic Energy
It is a force exerted by the substance per unit area on another substance. The force exerted by the gas on the wall of its container.
Pressure
P=F/A
Due to the negligible and large intermolecular spaces between gases, when your classmate farts in gets spread across the room. What characteristic of gas explains this?
Diffusion or Diffusibility
What property will measure the average kinetic energy of gases?
Temperature.
The faster the gas molecules move, the hotter the substance. The slower, the colder.
What gas is the most abundant in our atmosphere?
Oxygen
The amount of gas (n) or the number of atoms or particles is measured in ______?
Moles
1 mole=6.022 X 1023
the attractive and repulsive forces that arise between the molecules of a substance.
Intermolecular forces
We feel uncomfortable in our room during the hot weather because there is too much water vapor coming from our sweat. What do you call the amount of water vapor in the atmosphere that gives us the irritating feeling.
humidity
Correct the statement if it is wrong:
Gases have no definite shape and volume.
The statement is correct.
Gases have no definite shape and volume.
He was the scientist that identified the amount of atoms or particles present in 1 mole of substance like gas which is equal to 6.022 X1023.
Lorenzo Romano Amedeo Carlo Avogadro
The theory that explains how gases behave.
Kinetic Molecular Theory
Gases move at 500 m/s. If Travis has a cold and sneezes in front of the room, how fast will the viral particles from his sneeze reach Jiroh who is 9 meters away from him?
t=d/v
t=9m/500 m/s
t=0.018 s
