Answer:
Although the inner core is very hot, it is solid because it is experiencing very high pressure.
The outer core is not under enough pressure to be solid, so it is liquid even though it has a composition similar to the inner core.
Explanation:
The state of matter (solid, liquid or gas) of a given material depends on its temperature and pressure.
Answer:
It is important for future generations to study current environmental issues because it can help better the future and help the current issues from getting any worst.

Answer:The pressure of Mercury = 588,600Pa
Explanation:
The pressure of Mercury is given as
p=h x ρ x g
Where h =height= 20 dm
changing to meters
10 decimeters (dm) =1 meter
20dm =2 meter, 2m
ρ is the density =30000-kg/m³
g , gravity = 9.81-m/s²
Pressure = 2.0m x 30000-kg/m³ x 9.81-m/s²
588,600 kg.m/ s²/m² =588,600 N/m²
The pressure of Mercury=588,600Pa
Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy. ... The binding of a substrate to an enzyme active site is termed the "enzyme-substrate complex.
