Question

if we go to space without space suit then what happens​

Answer 1

At most, an astronaut without a suit would last about 15 seconds before losing conciousness from lack of oxygen. ... If he hadn't, the vacuum would have caused that oxygen to expand and rupture his lung tissue, forcing fatal air bubbles into his blood vessels, and ultimately his heart and brain.

Answer 2

Answer:

Astronauts need space suits to stay alive. You could only last 15 seconds without a spacesuit — you'd die of asphyxiation or you'll freeze. If there's any air left in your lungs, they will rupture.
