Q.

Why do the molecules move freely in liquids?

Q.

Identify the error in the given statement. Circle the incorrect word and write the correct word in the blank.

Due to the presence of more intermolecular space between the molecules of liquids, they possess high density than solids.

Q.

In liquids, the molecules are

1. held together by attractive intermolecular forces

2. able to move past one another freely

3. both a and b

4. neither a nor b

Q. The given graph represents the variation of Z (compressibility factor) vs. P for three real gases A, B and C. Identify the correct statement

1. For the gas A, $a=0$ and its dependence on P is linear at all pressure
2. For the gas B, $b=0$ and its dependence on P is linear at all pressure
3. For the gas C, which is typical real gas for which $a\ne 0,b\ne 0$. By knowing the minima and the point of intersection with $Z=1,a$ and b can be calculated
4. At high pressure, the slope is positive for all real gases
