Which is not a characteristic of a compound? Different samples have different properties Can be represented by a chemical formul
1 answer:
Out of all given choices, “Different samples have different properties” is not a characteristic of a compound
Answer: Option A
<u>Explanation: </u>
A substance which comprises of more than one element chemically linked together at a fixed weight ratio usually referred as compound. The relationship arises due to the result of the chemical reactions between the components of the elements.
The property of the compound vary from the property of its elements to which it gets formed. For example: Water () is a combination of two elements, hydrogen and oxygen, chemically bonded in a constant 1: 8 weight ratio

The rate of change of vertical pressure is directly proportional to density and also directly proportional to temperature.
Generally, the relationship between temperature, density and rate of vertical pressure is given as;
where;
- <em>ρ is density</em>
- <em>T is temperature</em>
- <em>dP is rate of change of vertical pressure</em>
Thus, from the formula above, we can conclude the following relationship between temperature, density and the rate of vertical pressure change in spatial pattern of heights.
The rate of change of vertical pressure is directly proportional to density and also directly proportional to temperature.
