How can pressure be increased or decreased?
Increase pressure: decrease volume, increase temperature, increase moles of substance. Decrease pressure: do the reverse
When temperature decreases what does the volume of liquid water do increase or decrease?
The volume of water increase under 3,98 oC.
What 2 things can make the pressure of gas rise?
1) Increase in heat 2)Decrease in volume
What gas law describes when adding gas to a balloon will cause the volume to decrease?
The volume decrease only when the external pressure increase.
When volume is increased does pressure increase or decrease?
Neither. Volume is independent of mass. Effectively, if you increase the volume of a substance you are moving the particles that comprise that substance apart. Eventually, you would have a gas which expands to fill the volume of its container.
How does temperature affect the volume of substance?
An increase in temperature will cause an increase in volume, while a decrease in temperature will cause a decrease in volume.
What causes density to decrease?
an increase in volume and/or a decrease in mass
Will increase the volume of the gas?
An increase of the temperature or a decrease of the pressure.
As the temperature of a fixed volume of a gas increases the pressure will?
decrease
How does a change volume affect an objects density when mass stays the same?
With constant mass, a decrease in volume will increase the the density. Conversely, an increase in volume will decrease the density.
How can pressure be increased or decreased?
Increase pressure: decrease volume, increase temperature, increase moles of substance. Decrease pressure: do the reverse
How bronchial asthma effect on lung volume and capacity increase or decrease and why?
decrease -
If the volume and number of moles of gas are held constant as the temperature increase what will the pressure do?
The volume decrease.
Will the volume of oxygen increase or decrease after burning?
oxygen is used ... volume decreases.
When the volume of gas decreases would the pressure increase or decrease?
It would increase.
When temperature decreases what does the volume of liquid water do increase or decrease?
The volume of water increase under 3,98 oC.
What gas law describes when adding gas to a balloon will cause the volume to decrease?
