Liquid substance expand more than ………states of matter.
a) solid
b) liquid
c)gasd
d) none
Thermal Expansion In Solids:
When a solid is heated, its atoms vibrate faster about their fixed points. The relative increase in the size of solids when heated is therefore small.
In which of the following state of matter, the particles vibrate about their mean position but don’t leave their positions?
a) solid
b) liquid
c) gaseous
Why solids expand on heating?
a) their particles vibrate with greater amplitude
b) the gap between neighboring atoms increases
c) vibrational kinetic energy of their particles increases
d) all of these
Why solids contract on cooling?
a) their particles vibrate with smaller amplitude
b) the gap between neighboring atoms decreases
c) vibrational kinetic energy of their particles decreases
d) all of these
Why solids contract on cooling?
a) their particles vibrate with greater amplitude
b) the gap between neighboring atoms increases
c) vibrational kinetic energy of their particles increases
d) none of these
