True or False: A mixture of combustible gas and air will explode when exposed to an open flame.
Error: A mixture of combustible gas and air does not necessarily explode when exposed to an open flame; this is because if the ignition point of the mixture is below the lower limit or above the upper limit, neither explosion nor combustion will occur. However, if a mixture with a concentration higher than the upper explosion limit leaves a sealed container or space and comes into contact with air again, it remains at risk of burning or exploding.
Error. A certain concentration range needs to be achieved.
