Solute is a substance that dissolves in a solvent in order to form a solution. Solutes can be in liquid, gaseous or solid phase. Normally, in a solution, solutes are in a lesser amount than the solvents. When a solution has the maximum amount of solutes it can dissolve, then the solution is said to be saturated.
Answer:
Amount of heat absorbed by water is 2604.54 J.
Explanation:
Amount of heat absorbed by water = 
where m represents mass, C represents specific heat and
represents change in temperature.
Here
g ,
and
= (final temperature - initial temperature) = (29.5-21.2)
= 8.3
So, amount of heat heat absorbed by water
= 
= 2604.54 J
<span>In a chemical change, the molecular structure of a substance changes. I think this is right. I hope this helps.</span>
I’m distilled water all of the dissolved substances mixed in water have been removed by evaporation.
Explanation:
According to Boyle's law, pressure of a gas is inversely proportional to its volume at constant temperature and moles.
Mathematically, P = 
where, k = proportionality constant
Also, formula for initial pressure and volume is as follows.

or, 
=
= 30 atm L
Now, we will calculate the value of
as follows.

= 
= 30 atm L
Hence, as
this means that it signifies that gas obeys boyle's law.
