As you get higher the atmospheric pressure lowers. The pressure in the packet of crisps has the pressure at which it has been closed (pressure at the surface of the earth). This means that the air molecules in the packet press harder outside than the air molecules in the atmosphere press on the packet.
Explanation:
The grey powder of silver ( I ) oxide i.e. Ag₂O breaks down to give a metal called the silver metal and an odorless , colorless gas , which is the oxygen gas .
The balanced chemical reaction is as follows -
Silver oxide -----> Silver + oxygen
Ag₂O ------> Ag (s) + O₂ (g)
The balanced reaction is -
2 Ag₂O (s) ------> 4 Ag (s) + O₂ (g)
We are not given the diagram needed for this question so it would be better to talk about how to determine which object would be the most dense and least dense. One way to determine this is by looking at the densities of these objects. Higher value means the most dense while the lower value is the opposite.
Triangles may be regarded as similar or congruent on the following basis;
1) Side angle side (SAS)
2) Side side side (SSS)
3) Angle Angle side (AAS)

What is a triangle?</h3>
A triangle is a three sided figure. The figures are not shown here. However, two triangle may be regarded as similar or congruent by the following conditions;
1) Side angle side (SAS)
2) Side side side (SSS)
3) Angle Angle side (AAS)
Since the triagles are not shown here, the similarity of the triangles can not be established.
