Answer:
pressure and temperature are directly proportional.
Explanation:
At constant temperature and pressure the volume of a gas is directly proportional to the number of moles of gas. Also given a constant temperature and volume the pressure of a gas is directly proportional to the number of moles of gas.
This means that if V is constant then
P = n (RT/V) then n= PV/RT. As P is increased, T is also increased thereby decreasing the value of n since pressure and temperature are directly proportional.
Hydrogen exhibit similar properties with lithium because both are in the same group 1 as they both have a valence electron of 1
- Hydrogen also exhibit some similar properties with fluorine simply because they are both non metals
<h3>What is an element?</h3>
An element is a substance which cannot be split into simpler forms by an ordinary chemical process. This simply goes to say that elements are substances which cannot be decomposed into simpler substances by ordinary chemical reactions.
An atom is the smallest unit or part of an element which can take part in a chemical reaction.
On a general note, elements are classified as thus:
- Metals, non-metal, and metalloid.
- The extreme left side elements in the periodic table are metals, for example, aluminum, sodium, calcium, caesium, etc.
- However, elements on the right side are generally referred to as non-metals, carbon, chlorine, oxygen,
So therefore, hydrogen exhibit similar properties with lithium because both are in the same group 1 as they both have a valence electron of 1
- Hydrogen also exhibit some similar properties with fluorine simply because they are both non metals

The answer is dissolved in water, because in chemistry, (aq) is shorthand for aqueous solution.
