Katrina inserts a key into her car’s ignition. She turns the key, putting her car into ignition mode. In this mode, some energy
is used to increase the temperature of the car’s fuel. This energy allows the fuel to combust and the car to move. What’s this energy called? absorbed energy
activation energy
chemical energy
released energy
solar energy
The fuel used in car is petroleum product which is a fossil fuel. Petroleum products such as petrol or diesel are chemical compounds in which chemical energy is stored in their bonds. When these compounds undergo chemical reactions, resulting in breaking of bonds and releasing energy. When ignition of a car is on, the energy is released when chemical bonds are broken. The released energy is carry out work in the car system.
Answer: The room temperature thermal energy is about 2.5 KJ/mol, where areas hydrogen bond energy is in the range of 6-15 KJ/mol. So it must not only for thermal fluctuations. (please be specific with reference)
