PRINCIPLES OF AIR PRESSURE IN OUR DAILY LIFE.

1. There are many tools in everyday life that function based on the principle of air pressure.

2. Below are some tools that depend on air pressure to operate.

3. The principal of air pressure can be used to solve problems in our everyday life such as clearing a clogged pipe using a suction pump and pouring condensed milk from a can.

Gas under high pressure

1. When a gas is placed under a sufficiently high pressure or is cooled sufficiently, it condenses and becomes a liquid.

2. The liquid will become a gas again when the pressure is released.

3. This property is used to store gases under high pressure in gas tanks and aerosol cans.

Safety measures when using gas under high pressure

The following safety measures must be followed when using gases under high pressure.(a) Place the gas tank upright.(b) Keep the gas tank away from heat sources (fire) or sunlight.(c) Light a match forst before turning on the gas.(d) do not store the gas tank in an enclosed space.(e) Do not throw aerosol cans into a fire as they will explode.(f) Turn off the gas supply when you do not need it any longer.(g) Check to ensure that all mgas tubes and connections are tight and do not leak.(h) Used a soap solution to cheak for leaks along gas tubes and connections.
