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

Race deals with biology; on the contrary ethnicity is more of culture.
Ethnicity is a culture that is given to a specific region, for instance, language, religion, heritage as well as customs. To belong to a certain ethnic group one needs to conform to certain practices

Answer:
Water is a liquid at room temperature, but becomes a solid (called ice) if it is cooled down. The same water turns into a gas (called water vapor) if it is heated up. The changes only happen when the substance reaches a particular temperature. Water turns to ice at 32ºF (0ºC). This is known as its freezing point.
