what would happen to the boiling point of water at 8000 above sea level, where the air pressure is lower?

Answers

Answer 1

Answer:

Answer:

The boiling point will decrease to 73.3°C

Explanation:

Atmospheric pressure decreases with elevation and the boiling point of water is directly related to atmospheric pressure, it rapidly drops as elevation increases too, approximately 1°C for every 300 meters.

Answer 2

Answer: The boiling point will be lower, because water boils when its vapour pressure is equal to atmospheric pressure. If you are at 8 000 m above sea level, the air pressure is lower than one atmosphere and the equilibrium between the water and air pressures will be reached before.

Name two metals alloyed with iron to make stainless steel.

Answers

For stainless steel different kinds of compositions are used. Based on that different series of stainless steel has been coined.
1. Series 200 - Iron alloyed with chromium, nickel and manganese.
2. Series 300 - It has
a. Stainless Steel 304 - it has composition of 18% chromium and 8% Nickel
b. Stainless Steel 316 - This has 18% chromium and 10% Nickel

Each kind of stainless steel is of different cost and has different applications.

PLEASE HURRY. Which of the molecules below is propyne?

Answers

Answer: Option (D) is the correct answer.

Explanation:

General formula of an alkyne is $C_(n)H_(2n-2)$ .

Suffix "yne" in the name of a compound represents that there is a triple bond present in the compound.

So, a molecule of propyne will have three carbon atoms, four hydrogen atoms and a triple bond. Therefore, there wll be 6 sigma bonds and 2 pi bonds in a propyne molecule.

The last photo because its molecular formula is C3H4.

Which describes the polarity in a water molecule?

Answers

Answer:

The oxygen atom in a water molecule is strongly electronegative. The atoms of the water molecule are held together by covalent bonds. water has nonpolar bonds, but it has a bent shape and is therefore polar.
