Answers

1
As the atmospheric pressure increase, the column of mercury in a barometer:
increases in height
decreases in height
remains the same
increases or decreases depending on height.
2
What is standard temperature?
none of these
298 K
25 °C
0 °C
3
If atmospheric pressure is 790 mmHg, what is the pressure of the gas in the flask?
790 mmHg
cannot be determined
820 mmHg
760 mmHg
4
If the volume of a gas is doubled, what will happen to its pressure?
It will be unchanged
it will be cut in half
need more information to answer.
It will double
5
Why does the pressure of a gas increase?
B. more forceful collisions with the wall of a container.
A. more collisions with the wall of a container.
Both A & B
C. less collisions with the wall.
6
What is NOT part of the kinetic molecular theory?
When placed in a smaller volume gas particles collide more
all of these are part of kinetic molecular theory.
gas particles are in constant random motion.
gas particles stick to each other when they collide.
7
If the number of gas particles in a container is doubled, what will happen to the pressure?
more information is needed to answer
it will remain constant
it is cut in half
it is doubled
8
When the temperature of a gas changes from 60 °C to 30 °C, how does the pressure change
it doubles
it is cut in half
depends on the identity of gas
it decreases by a small amount
9
How does a thermometer measure temperature?
placing it in ice water
placing it in boiling water
by measuring speed of each particle
liquid expansion & contraction
10
What is standard pressure
760 mmHg
1 atm
both 760 mmHg & 1 atm
none of these
11
A gas at 1 atm & 25 °C is cooled to 0 °C. By what factor do you multiply by to find new P?
273K/298K
0°C/25°C
25°C/0°C
298K/273K
