You are true, Stokey. The correct choice is<em> (c)</em>.
If you think about it a little bit more, you'll realize that "side to side" is also a horizontal motion.
Anyway, the question told us that we're only talking about 2 dimensions. Well, the The measurements in the 2 dimensions are the x and the y . If there were a z measurement, that would be the 3rd dimension.
Answer:
Volume will increase by factor 2
So option (A) will be correct answer
Explanation:
Let initially the volume is V pressure is P and temperature is T
According to ideal gas equation
, here n is number of moles and R is gas constant
So
....................eqn 1
Now pressure is doubled and temperature is quadrupled
So new volume
........eqn 2
Now comparing eqn 1 nad eqn 2

So volume will increase by factor 2
So option (A) will be correct answer
