If the temperature of a fixed quantity of gas decreases and the pressure remains unchanged
volume will increase
its density decreases
volume will decrease
volume will not change
If I add more air to a balloon, the volume will increase. Which gas law describes this?
Gay-Lussac's law
Charles's law
Boyle's law
Avogadro’s law
Dalton's law of partial pressures
What is the result of a force distributed over an area?
Mass
Temperature
Pressure
Kinetic energy
Volume
Scuba divers must be careful not to come to the surface too quickly because as the pressure is reduced, the volume of gasses in their bloodstream expands. Which gas law describes this?
Gay-Lussac’s law
Avogadro’s law
Boyle’s law
Charle’s Law
Dalton's law of partial pressures
Diffusion between two gasses occurs most rapidly if the gasses are at
low temperature and the molecules have a low molar mass
high temperature and the molecules have a high molar mass
high temperature and the molecules have a low molar mass
high temperature and the molecules have high molar mass
If the pressure and temperature of a gas are held constant and some gas is added to the container or some is allowed to escape, what changes can be observed?
Moles
Volume
Rate of Diffusion
Chemical Properties
Which would exert more pressure on the ground?
A brick laying on its side
A brick laying flat
Both would exert the same pressure
A brick laying on its end
The gas pressure inside a closed container decreases when
the temperature is increased
the number of gas molecules is increased
the number of gas molecules is decreased
the temperature is decreased
the number of molecules is increased, and the temperature is increased
Why does a can collapse when a vacuum pump removes air from the can?
The unbalanced outside force from atmospheric pressure crushes the can
The inside and outside forces balance out and crush the can
The atmosphere exerts pressure on the inside of the can and crushes it
The vacuum pump creates a force that crushes the can
Why does the air pressure inside the tires of a car increase when the car is driven?
The atmosphere compresses the tire
Some of the air has leaked out
The air particles collide with the tire after the car is in motion
The air particles inside the tire increase their kinetic energy because their temperature rises
Which is an example effusion?
helium dispersing into a room after a balloon pops
oxygen and gasoline fumes mixing in an automobile carburetor
the aroma of a cooling pie spreading across a room
air escaping from a pinhole in a tire
If a gas with an odor is released in a room, it can quickly be detected across the room because it
condenses
effuses
is compressed
diffuses
is dense
Pressure cookers (instant pots) are used to cook food faster since it's enclosed and the temperature is increased. Which gas law describes this?
Charles's law
Boyle’s law
Avogadro’s law
Gay-Lussac's law
Dalton's law of partial pressures
If a balloon is placed in a freezer, the volume will decrease. Which gas law describes this?
Gay-Lussac's law
Charles's law
Avogadro’s law
Boyle's law
Dalton's law of partial pressures
Which instrument measures atmospheric pressure?
Barometer
Torrometer
Vacuum Pump
Manometer
According to Avogadro’s law, 1L of H2(g) and 1 L of O2 (g) at the same temperature and pressure
contains 2 moles of gas each
have unequal volumes
have the same mass
contain equal numbers of molecules
I LOVE YOU MY LOVE HEATHERRRR
loll
I love you too
I love you so muchhh my handsome king, who is the loml
no.
