Given below are two statements:
Assertion (A): | At constant temperature, pV vs p plot for real gases is not a straight line. |
Reason (R): | At high pressure, all gases have Z>1 but at an intermediate pressure most gases have Z<1. |
1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
3. | (A) is true but (R) is false. |
4. | (A) is false but (R) is true. |
A: At Boyle's temperature, the compressibility factor of gas approaches unity.
R: At Boyle's temperature the real gas obeys ideal gas law.
1. Both assertion & reason are true and the reason is the correct explanation of the assertion.
2. Both assertion & reason are true but the reason is not the correct explanation of the assertion.
3. Assertion is a true statement but reason is false.
4. Both assertion and reason are false statements.
In the given figure, the curve representing an ideal gas is-
1. B only
2. C and D only
3. E and F only
4. A and B only
Consider the following graph:
The curve that represents CO2 gas is -
1. X
2. Y
3. Both X and Y
4. Cannot predict from the graph
