Question

Burning vaporized gasoline in a combustion chamber results in high heat and a rapid _______ of gases. A. contraction B. explosion C. expansion D. neutralization

Answer 1

cut off the O2 supply (smother fire with water, blanket, CO2), allow fuel source to be totally consumed (wait it out), or reduce temperatureflash pointlowest temperature at which a flammable liquid gives off sufficient vapor to support a flameignition temperaturethe temperature which inputs sufficient energy to surmount activation energy

Answer 2

The correct option is C.
The combustion chamber is an internal combustion engine in which fuels are burned in a confined space. The reaction of the fuels with oxidizers in the combustion chamber is an exothermic reaction, that gives off heat into the environment. The reaction makes the gases to possess high temperature and pressure which makes them to undergo expansion.
