Answer:

  C. The boiling point of water

Explanation:

We assume your question is the one attached.

Obviously, the shape of the (liquid) water is a function of the container it is in, as it is for any liquid or gas.

The rate of evaporation will depend on the temperature and on the surface area. The different containers are different in both ways, so evaporation is not a constant.

The boiling point is a physical property of the water, so will be the same across all containers.

The amount of steam released is related to the rate of evaporation. It will not be a constant across the different containers.

__

The appropriate choice is ...

  The boiling point of water

Where do you find an elements energy levels
ahrayia [7]
You can find an element's amount of energy level by determining their place on the periodic table. An element's amount of energy levels are represented by which period/ row they are in. For example, Calcium has 4 energy levels. I know this because it is in the fourth period on the table.

Hope this helps!

Why does a 4 carbon linear alkane, butane c4h10, have two more hydrogens ?
Scilla [17]
Alkanes are hydrocarbons that only contain single bonds in them. A carbon can bond with up to 4 atoms, even with another carbon atom. So, in a C-C bond, 3 more H atoms can bond to each of the C atom. Generally, the chemical formula for alkanes is CₓH₂ₓ₊₂. So for butane, there are 4 C atoms. The corresponding H atoms are 2(4) + 2 = 10. That's why it's chemical formula is C₄H₁₀.
