Answer:
Scientific Explanation of weather change and cause storms is described below in detail.
Explanation:
The weather is just the nature of the environment at any time, including items such as warmth, rainfall, air pressure, and cloud shelter. Daily variations in the weather are due to storms and winds. Seasonal variations are due to the Earth spinning nearby the sun. Warm beginnings often produce stormy weather as the heated air mass at the exterior rises above the cool air mass, creating clouds and storms.
Answer:
If temperature increases, as it does in most reactions, a chemical change is likely to be occurring. This is different from the physical temperature change. During a physical temperature change, one substance, such as water is being heated.
Explanation:
Almost all properties are common to elements within a single group on the periodic table. They react with water in the same way, they have the same number of valence electrons thereby having the same valency, the number of shells in the atom of the element increases by one as we move down the group.
In general, they have the same chemical properties as chemical properties depend on the number of electrons in the valence shell i.e. the outermost shell in the atom of an element.
They are pretty much the cause and effect. The independent variable that is being changed in the experiment, so it is the cause. The dependant variable is the result of change the independant variable, so the effect.
Explanation:
A property which does not bring any change in chemical composition of a substance is known as physical property.
For example, blood is more viscous than water, its pH is slightly alkaline, its temperature is about 
(
) .
On the other hand, a property which changes chemical composition of a substance is known as a chemical property.
For example, precipitation, reactivity, toxicity etc are chemical property.
Sometimes, the change in color of a substance can also occur due to a chemical change.
Thus, we can conclude that following are the physical characteristics of blood.
- it is more viscous than water.
- its temperature is about ().
- the pH is slightly alkaline.
- it is about 8% of one’s total body weight.
