Answer:
Well it's your homework
You should do it by yourself
Just kidding
Explanation:
Well here is the answer
1) Expansion is the propensity of metal to expand after getting heat.
Contraction is the tendency of a metal to contract after getting cooled.
Some metals are Gold, Aluminium, Copper, and Silver.
2)Metal rim is made narrowly tinier than the wooden wheel. On heating, the rim expands and fits into the wheel. Coldwater is then spilled over the rim, which contracts and fits tightly onto the wheel.
3) Solubility is the ability of a solid, liquid, or gaseous chemical solute to dissolve in a solvent to form a solution.
In Gases and Liquids, The kinetic energy increases and they try to escape which results in decreasing in their solubility. While in solids when there is an increase in kinetic energy, it comes with higher temperatures that allow the solvent molecules to more effectively break apart the solute molecules that are held jointly by intermolecular attractions.
4) Respiration is a biological process within living organisms, where the storage food is oxidized in the presence of oxygen and releases carbon dioxide and Energy.
C6H12O6 + O2 -> CO2 + Energy
The energy released during respiration is used for carrying out various life processes.
