Measuring the heat of chemical reactions or physical changes.
Explanation:
The range of a data set is the difference between the highest and lowest value in a given set.
Calculating the range of a data set gives the spread of the data set.
In order to calculate the range of a data set;
- the highest number must be known
- the lowest number must be known
The difference between the highest and lowest number gives the range.

<h3>Answer</h3>
At a high temperature above 20° oxygen solubility starts to decrease.
<h3>Explanation</h3>
Oxygen, O2 is a very essential component of water as we can see in its chemical formula h2O.
The solubility of oxygen decreases as temperature increases. This means that warmer water will have less dissolved oxygen than does cooler water.
<h3>Other factors that affects oxygen solubility in water</h3>
Salt levels
higher the salt levels in water, lower will be oxygen in it.
Pressure
Water at lower altitudes can hold more dissolved oxygen than water at higher altitudes because dissolved oxygen will increase as pressure increases.
