explain the term expansion in solids and expansion liquids?
Answers
Answer:
solid is very evident in solids as atoms are dencily packed . example: wood
Explanation:
when some get heat liquid will flow
example:milk, oil, water
Answer:
When a balloon is ruptured suddenly, or a tyre is
punctured suddenly, the air inside the balloon/
tyre rushes out rapidly to the atmosphere.
This process (expansion of air inside the
balloon/tyre) is so quick that there is no ime for
transfer of heat from the system to the surroundings
or from the surroundings to the system. Such an
adiabatic expansion is called free expansion. It is
characterized by Q = W=0, implying A U=0. Free
expansion is an uncontrolled change and the
system is not in thermodynamic equilibrium. Free
expansion cannot be illustrated ith a P-V
diagram as only the initial state and final state are
known.
