5 0
What they breathe is compressed air. Yes normal air that every one breathes. This is compressed to 200bar and can last for approx. half an hour depending on the diver. What is exhaled is is also the same, namely carbon dioxide. 
<span>Sometimes divers mix gases to different ratios to give themselves longer dive times. This is called 'Ni-trox', which means ( Nitrogen/ Oxygen mixture). The gases exhaled are slightly different. </span>

How many neutrons are in the nucleus of an atom that has an atomic mass of 36 and an atomic number of 25?
elixir [45]

Answer:

Neutrons = 11

Explanation:

To get the number of neurons an element has you have to subtract the number of protons from the atomic mass of that element.

The number of protons is equal to the atomic number of that element.

Atomic number = Number of Protons

So the number of protons is 25

Neutrons = Atomic mass - Number of Protons

Neutrons = 36 - 25

Neutrons = 11

When heat is applied gradually and evenly to solid ice at 0 Celsius, it melts. Does the temperature change while it is melting t
serious [3.7K]

No, the added heat melts the ice, but the result is water at the same temperature. Hence, option B is correct.

<h3>What is temperature?</h3>

The degree of hotness or coldness is measured on a definite scale.

Temperature doesn't change as heat is added during a phase change; for example, when the ice melts.

During the phase change, the added heat doesn't make the molecules move faster, but rather further apart.

Thus, No, the added heat melts the ice, but the result is water at the same temperature.
