Older MCQs might not have the typical A, B, C,
D
choices. They
have choices 1, 2, 3, and a combination of them is the answer. Below is the key that maps such
combinations to the answer.
A
1, 2 and 3 are correct
B
1 and 2 only are correct
C
2 and 3 only are correct
D
1 only is correct
Explain qualitatively, in terms of particles, the relationship between: (a) pressure and temperature at constant volume (b) volume and temperature at constant pressure (c) pressure and volume at constant temperature
Explain, in terms of the motion and arrangement of particles, the thermal expansion of solids, liquids and gases, and state the relative order of magnitudes of the expansion of solids, liquids and gases
Know the terms for the changes in state between solids, liquids and gases (gas to solid and solid to gas transfers are not required)
