Explanation
Oxy-hydrogen flames are produced by the combustion of hydrogen and oxygen. This reaction is highly exothermic, meaning it releases a large amount of heat. The temperature of an oxy-hydrogen flame can reach around 2800°C, which is hot enough to melt many metals. This high temperature and the significant amount of heat evolved are the primary reasons why oxy-hydrogen flames are used for welding and cutting metals. While hydrogen does combine explosively with oxygen, the controlled use of the oxy-hydrogen torch harnesses the heat from this reaction for industrial purposes, rather than simply for the explosive property.
it evolves alot of heat wen burnt days is used in oxy-hydrogen flames for cutting n melting metals.
is correct.when u hav oxygen in hydrogen container u exprnx heat wch do come in excex {i do need a serious friend boy/girl that hav sometin upsterx.}add me up on fb "Ify galore" or in 2go 'presido804'
