What keeps the rate of burning in check is the rate at which oxygen can reach the burning oil surface. None of these experiments produce the same incredible explosion as the difluoroethane and water. More precisely, its due to the difference in their temperature and due to vigorous transfer of thermal energy from hot oil to cold water where water instantly changes its state into vapour. Pressure change leads to volume change; agreed. So I bought a hot sauce I had have bought before from a taco spot down the street and they have a habenero salsa with ingredients 'habenero lime juice salt' and apon opening it, it started to bubble up then about two seconds later bursted out all â¦ The effect depend on The chance of a re from heating oil is extremely remote.
