Which of these would have the lowest kinetic energy?
2 answers:
Answer: ice water
Explanation: Kinetic energy is the energy possessed by a substance by virtue of its motion and is directly proportional to the temperature of substance.
R= gas constant
T= temperature
Thus boiling water will have a temperature of around , ice water will have a temperature of
, refrigerated water will have a temperature of more than
, and water at room temperature will have a temperature more than refrigerated water but less than boiling water.
Thus ice water has lowest temperature and thus will have lowest kinetic energy.

There are three carbon and 8 hydrogen present in propane molecule. The Lewis structure of propane is shown as:
Three molecules of such carbon atoms bound to eight molecules with hydrogen atoms make up the organic complex propane molecule.
It is known that carbon has 4 valence electrons and hydrogen has one valence electron. Carbon needs 4 extra electrons to complete its octet hence, it will share its electrons with with 4 hydrogen atom and complete its octet.
Carbon will be formed 4 bond . Three bond with hydrogen and one bond with carbon atom.
