If you mean 'Why do climbers carry oxygen cylinders on mountains' then that is to survive. On high mountains like Mount Everest the air (oxygen) is so thin you need help to breathe, so they use oxygen from a cylinder.
because external pressure is low on the montains and food dont cook easily that is why mountainers carry with them pressure cooker........
A climber carries an oxygen cylinder on their back because it helps him/her to breathe easier. On high altitude mountains like Mount Everest the air is so thin it makes it very hard for anyone to breathe without extra oxygen from a cylinder.
