Answer:
b
Explanation:
wave transfers energy from one place to another
Answer:
Pressure=3.91atm
Explanation:
As given in the question that gas is ideal so
we can use Ideal gas equation
volume of gas is not given directly but volume of container is given and we know gas takes the volume in which they are kept.
therefore mole remains contant
P1=2.5 atm
V1=2L
T1=320K
P1=?
V1=1L
T1=250K
..............(1)
................(2)
eqn2/eqn1
Pressure=3.91atm
Exam board websites often have past papers from several previous years, if you know what exam board you are going to be using, try that, if not there may be content on the edexcel and AQA websites
Answer:
The average pressure in the container due to these 75 gas molecules is
Explanation:
Here Pressure in a container is given as
Here
- P is the pressure which is to be calculated
- ρ is the density of the gas which is to be calculated as below
Here
mass is to be calculated for 75 gas phase molecules as
Volume of container is 0.5 lts
So density is given as
- is the mean squared velocity which is given as
Here RMS is the Root Mean Square speed given as 605 m/s so
Substituting the values in the equation and solving
So the average pressure in the container due to these 75 gas molecules is
