Answer:
ionic.
Explanation:
the electronegativity difference is greater than 1.7.
Answer:
Wavelength, distance between corresponding points of two consecutive waves. ... Wavelength is usually denoted by the Greek letter lambda (λ); it is equal to the speed (v) of a wave train in a medium divided by its frequency (f): λ = v/f.
Explanation:
The answers to include the following below:
- Hot water has more energy than cold water because it has more internal energy present in it.
- The relationship between temperature and the movement of particles is a direct one which means that as temperature increases, the movement of particles also increases and vice versa.
- The temperature of a substance is directly proportional to the average kinetic energy of the substance which makes their relationship a direct one.
- Water is referred to as pure substance because it contains only one type of molecule.
<h3>What is Temperature?</h3>
This is described as the measure of the hotness or coldness of a substance and is influenced by heat energy.
Temperature has a direct relationship with average kinetic energy and movement of particles which means that an increase in one variable will also lead to a corresponding increase in the other.
This is the therefore the reason why the above answers are correct and the most appropriate.
