Can we hear in space, How do aeroplanes fly, in which state a liquid stays in space... facts, why

 Welcome to SSA 

Q1) Can we hear in space

Ans-Sound needs a medium to travel, space is almost vaccum, so sounds can't travel in space, so we can't hear any sound 

Did you know!  If sound travels through space then sounds from Sun can reach earth and it can cause worst effects on human hearing, because on Sun a lot of volcanic activities happening every minute, now we can image the sound of volcano eruptions travelling to earth then none of the humans can hear as every time there is unnecessary sound 

Q2) How do aeroplanes fly 

Ans- Aeroplanes work in a principle called lift it is about pressure difference, now I will tell what's lift

When an aeroplane starts to run on runway then the air above the wings blow off , this creates a low pressure region above the wing and a high pressure at bottom, so due this pressure differences aeroplanes lift off, this maintains the balance of aeroplanes

Did you know! Aeroplanes change their direction through a pane at the back upper wing

Q3) In which state a liquid stays in space 

ans- Solid state

According to the astronauts who've seen it for themselves: When the astronauts take a leak while on a mission and expel the result into space, it boils violently. The vapor then passes immediately into the solid state (a process known as desublimation)

Did you know! In international space station (ISS) is where astronauts live in earth's orbit with zero gravity for a specific period of time, there they do a lot experiments, even this water exists in solid form can observed here clearly, it exists somewhat in a jelly form.

Hi viewers This is SSA from Learn it, Sai group,  I try to spread information through my blogs and websites. Our motto of this group is Information should be free. Nowadays many schools have high fees, due to that many students are unable to study the basic concepts, now no problem I will reach u with a lot of topics covered.

Visit my blogs and stay tuned

Thank you 😊
