Explanation:
Shade only feels cooler because you are avoiding solar radiation. In reality, the temperature in the sun is the same as the temperature in the shade. ... When in the shade, your skin is not being “heated” by the sun's rays, so your skin and your body feel a more comfortable temperature.
<span>Ionic compounds form crystal lattices, not molecules. The term formula unit is used to indicate the simplest whole-number ratio of ions in the compound.</span>
When gases in containers are heated, their molecules increase in average speed. This means that they exert a greater force when they collide with the container walls, and also collide with the walls more frequently. The gas is therefore under greater pressure when its temperature is higher.
This is formula to find pH. -log[H^+]
now press calculator -log[4.7×10^11] and you will get 10.33
