Answer:
Step-by-step explanation:
Here, we want to get a tentative law from the given measurements
To get the correct options, we have to look at the values
Let us take a look at the options one after the other
a) Mass of gas is inversely proportional to the volume
What this mean is that as the mass of gas increase, the volume should decrease. Or as the mass decrease,the volume increase
Now, let us take a look at the values:
As mass increases from top to bottom, the volume also increases
This mean the law cannot be correct. This option is incorrect
b) Mass to volume ratio of a gas is constant
To check for this, we have to divide the mass by the volume for all the pairs
We can check for this as follows:
i) 22.5/1.6 = 14.0625
ii) 35.8/2.55 = 14.039
iii) 70.2/5 = 14.04
iv) 98.5/7.01 = 14.05
Looking at all the values, we can see that if we rounded them to the same whole number, we have 14 all through. That means the law is correct
This option is correct and should be selected
c) The mass of a gas is directly proportional to its volume
This is the direct opposite of the first option
We can see that as the mass increases,the volume also increases.That makes this option a correct one.
The option is correct and should be selected
d) The mass-to-volume ratio of a gas isn't constant
This is the opposite to the second option. We have proved and seen that the mass to volume ratio is constant.
This option is not correct and should not be selected
