If the temperature is increased What happens to the partial pressure of oxygen in a sample of air?
In a sample of air, an increase in temperature will result in an increase in the partial pressure of oxygen.
What happens to a fixed sample of gas when its temperature changes?
If a fixed sample of gas has a change of temperature pressure would increase.
If a fixed sample of gas increases in temperature it must also do what?
If a fixed volume of gas increases in temperature, it must increase in volume. If the gas is in a closed system, the pressure inside that system increases instead. When the gas increases in volume, it also decreases in pressure, often rising above colder, more dense gas if possible.
When a sample of gas is placed in a larger container at the same temperature what happens to the total force of the molecules hitting the walls?
The total force of the molecules hitting the walls (Pressure) will decrease if the volume is increased and the temperature stays the same. From PV = nRT, one can see that as V increases, P must decrease to maintain the same T.
As the temperature of a radioactive sample increases the rate of the nuclear decay?
It stays the same. Temperature has no effect on the rate of nuclear decay.
If a fixed sample of a gas increases in temperature at a constant pressure its volume does what?
Increases in direct proportion to the increase in temperature (on an absolute scale).
What happens to the thermal energy of a substance as its temperature increases?
When a sample of a substance absorbs thermal energy, its temperature rises.
If the temperature is increased What happens to the partial pressure of oxygen in a sample of air?
In a sample of air, an increase in temperature will result in an increase in the partial pressure of oxygen.
What happens to a fixed sample of gas when its temperature changes?
If a fixed sample of gas has a change of temperature pressure would increase.
The pressure of a sample of gas at 10.0 C increases from 700 mm Hg to 900 mm Hg What is the new temperature?
39.0
If a fixed sample of gas increases in temperature it must also do what?
If a fixed volume of gas increases in temperature, it must increase in volume. If the gas is in a closed system, the pressure inside that system increases instead. When the gas increases in volume, it also decreases in pressure, often rising above colder, more dense gas if possible.
When a fixed sample of gas increases in volume?
Decrease its pressure.
What happens to the sample mean as the sample size increases?
With a good sample, the sample mean gets closer to the population mean.
What happens to the expected value of M as sample size increases?
Decreases
When a sample of gas is cooled in a closed container the pressure inside the container?
increases......
When a sample of gas is placed in a larger container at the same temperature what happens to the total force of the molecules hitting the walls?
