In looking for other planets that might have life, astronomers focus especially on finding planets that

are the same size as earth
have rocky surfaces
have liquid water
have nitrogen-filled atmospheres

have liquid water

Explanation:

Liquid water and atmosphere are important for life to exist on a planet. Life can exist in the form of unicellular. It must not be multi-cellular organisms like animals.  A cell is majorly composed of water. Thus, liquid water is very essential for life to exist. All the life processes require liquid water. Thus, astronomers focus especially on finding planets that have liquid water.

with 5 seconds, no, but over time if the police car stays at 65m/s ad the speeding car stays at 60, then obviously yes, but the answer to your question would be, no.

hope this : )

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
