1) a = (v-u)/t
2) • least intermolecular force
• maximum intermolecular space
• gases neither have fixed shape nor fixed volume.
• It can be compressed .
• it can flow easily.
3) boiling occurr at fixed temperature and evaporation occur at less than boiling point.
Evaporation is natural whereas boiling is not natural.
4) The change of state from solid to gas directly is called sublimation.
eg - camphor
5) •When the body moves with uniform speed. Then, it is said to be in uniform motion.
• a=0
•When the body moves with non uniform speed. Then, it is said to be in non uniform motion.
• a is not equal to 0.
6) distance = 2πr/2
= 22×7/7
= 22 cm
displacement = diameter =2r
= 2×7
= 14
velocity = 14/10 = 1.4cm/s
speed = 22/10 = 2.2cm/s
