I can think of 2 off the top of my head first is friction and second is gravity
A combustion reaction usually happens when a hydrocarbon is reacted with an oxygen molecule producing water and carbon dioxide. It is an exothermic reaction which means it releases heat as the process proceeds. It is a spontaneous process where it readily happens without any supply of energy. The total kinetic energy of the reactants is greater than the activation energy that is why heat is being released. Acetic acid is a carboxylic acid and is classified as a hydrocarbon so when reacted with oxygen, it would yield carbon dioxide and water. The balanced chemical reaction would be as follows
CH3COOH + 2 O2 = 2 CO2 +2 H2O
Answer:
470 °C
Explanation:
This looks like a case where we can use Charles’ Law:

Data:
V₁ = 20 L; T₁ = 100 °C
V₂ = 40 L; T₂ = ?
Calculations:
(a) Convert the temperature to kelvins
T₁ = (100 + 273.15) K = 373.15 K
(b) Calculate the new temperature

Note: The answer can have only two significant figures because that is all you gave for the volumes.
(c) Convert the temperature to Celsius
T₂ = (750 – 273.15) °C = 470 °C
