Thermal Expansion In Fluids (Liquids And Gases:
Increase in dimensions of a liquid on being heated is called thermal expansion of the liquid. Types. Liquid has only volume. When heated, its volume increases. Increase in volume is called cubical expansion.
In which of the following state/s of matter, the particles are at large distance from each other than solid?
a) solid
b) liquid
c) gaseous
d) both b and c
Why liquids expand on heating?
a) the gap between their particles decreases
b) their force of attraction increases
c) their particles start moving with moving greater K. E
d) all of these
Why liquids contract on cooling?
a) their particles start moving with moving smaller K. E
b) the gap between their particles decreases
c) vibrational kinetic energy of their particles decreases
d) all of these
What happens to all three states of matter on heating?
a) they contract
b) they expand
c) they do not cchanged
d) all of these
What happens to all three states of matter on cooling?
a) they contract
b) they expand
c) they do not changed
d) all of these
