The substace at the end is the same as the colorless liquid
Explanation:
We know that it is a certainty based on things such as the size, mass, brightness, etc. They can determine to within a relative level of accuracy the age. Of course they can be off by millions of years, but that’s pretty precise for a 10–20 billion year time period for the life of a star. BUT we absolutely cannot predict exactly when it will explode and we see supernovas in other galaxies, but the last one in the Milky Way that we observed was in the 1600s.

Answer: Thus the pressure of the air in a car tire in psi is 25.4
Explanation:
Pressure is defined as the force exerted per unit area.
Thus units of pressure can be atm or psi or Pa.
Given :
Convert 1.73 atm to psi units
1 atm = 14.7 psi
Thus 1.73 atm =
Thus the pressure of the air in a car tire in psi is 25.4
