You are high up in the mountains and boil water to makesome tea. However, when you drink your tea, it is not as hotas it should be. You try again and again, but the water is justnot hot enough to make a hot cup of tea. Which is the bestexplanation for this result? (a) High in the mountains, it isprobably very dry, and so the water is rapidly evaporatingfrom your cup and cooling it. (b) High in the mountains,it is probably very windy, and so the water is rapidly evaporatingfrom your cup and cooling it. (c) High in the mountains,the air pressure is significantly less than 1 atm, sothe boiling point of water is much lower than at sea level.(d) High in the mountains, the air pressure is significantlyless than 1 atm, so the boiling point of water is much higherthan at sea level.
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
You are high up in the mountains and boil water to make
some tea. However, when you drink your tea, it is not as hot
as it should be. You try again and again, but the water is just
not hot enough to make a hot cup of tea. Which is the best
explanation for this result? (a) High in the mountains, it is
probably very dry, and so the water is rapidly evaporating
from your cup and cooling it. (b) High in the mountains,
it is probably very windy, and so the water is rapidly evaporating
from your cup and cooling it. (c) High in the mountains,
the air pressure is significantly less than 1 atm, so
the boiling point of water is much lower than at sea level.
(d) High in the mountains, the air pressure is significantly
less than 1 atm, so the boiling point of water is much higher
than at sea level.
