Answer: The main reason for the growth in demand for water is because of population growth
<em>Hardness is a measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied</em> <em>Macroscopic hardness is generally characterized by</em> <em>strong intermolecular bonds</em>, <em>but the behavior of solid materials under force is complex; therefore,</em> <em>there are different measurements of hardness</em>: <em>scratch hardness, indentation hardness, and rebound hardness. Hardness is dependent on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity. Common examples of hard matter are ceramics, concrete, certain metals, and super hard materials, which can be contrasted with soft matter.</em>
Answer:
C. metals
Explanation:
Elements in the periodic table are grouped into metal and non-metals depending on their characteristics. Metals usually possess the following characteristics:
- High melting and boiling point
- Brittle i.e. ability to break
- lustre i.e. ability to shine when polished.
- Good conductor of heat and electricity
Based on this above characteristics, element Q in this question is a METAL because it posseses the same qualities that a metal does.
Answer:
1.
