Answer:
There will be an increase in the level of nitrogen dioxide and a decrease in the level of ground-level ozone.
Explanation:
Ozone is a gas normally found in stratosphere, where it protects us from solar radiation. However, under certain circumstances, it can be formed on the ground level.
Conditions that have to be met in order for this to happen are existing of nitrogen oxides and volatile organic compounds (VOC) (both formed from the factories, industry and transport) and their reaction catalyzed by heat and light.
During dark, cold and cloudy days, due to the lack of heat and light from the Sun, formation of ozone will be decreased.
Also, this will enable building up of nitrogen dioxide, due to the same reason, leading to increased concentration.

Answer:
It reduces strength.
Explanation:
It not desirable to produce concrete mixtures of a higher consistency than normal because the strength of the concrete decreases. Consistency plays an important role in the determination of strength of concrete. Less water than normal quantity in concrete increases the consistency but decreases strength due to incomplete chemical reaction while on the other hand, adding more water would increase water-cement ratio and reduces consistency as well as strength of the concrete so that's why necessary amount of water and cement should be added to get higher strength.

Answer:
A) Between 1750 and 1760 many improvements were made. Improvements such as spinning and waving the coal on machines were examples of this.
B) Improvements such as said above helped dramatically. They helped by using their power to smelt iron and steel. Because of this, economic life improved.
C) Mining coal helped transform social and economic life. It transformed life because it pumps out deepening mines. Because of this, more and more power transfers to keep the machines running.
