Explanation:
Let's consider the unbalanced equation for the combustion of propane.
C₃H₈ + O₂ ⇒ CO₂ + H₂O
We will begin balancing H atoms by multiplying H₂O by 4.
C₃H₈ + O₂ ⇒ CO₂ + 4 H₂O
Now, we balance C atoms by multiplying CO₂ by 3.
C₃H₈ + O₂ ⇒ 3 CO₂ + 4 H₂O
Finally, we get the balanced equation multiplying O₂ by 5.
C₃H₈ + 5 O₂ ⇒ 3 CO₂ + 4 H₂O
The sum of the coefficients is 1 + 5 + 3 + 4 = 13.

Answer:
Heating water until it boils. The water particles would gain thermal energy from the heat source and there would be an increase in the kinetic energy between the water particles. During this stage, the temperature of the water particles remains the same as the thermal energy is used to break the strong bonds of attraction between the water particles so that they can be further apart and transition from the liquid state to the gas state.
