What happens to the pressure in a fluid as the depth increases?
The pressure decreases
The pressure remains constant
The pressure increases
The pressure fluctuates
Explain what pressure is and how it is defined. Provide examples of everyday situations where pressure is encountered.
Discuss the relationship between pressure and depth in a fluid. How does pressure change with increasing depth?
Describe the unit commonly used to measure pressure and provide its definition. How is it related to other units of measurement?
Pascal's principle states that:
Pressure in a fluid decreases with depth
Pressure in a fluid is directly proportional to its density
Pressure applied to a fluid is transmitted equally in all directions
Pressure in a fluid increases with temperature
According to Pascal's principle, an increase in pressure applied to a confined fluid will result in:
An increase in the fluid's volume
A decrease in the fluid's density
A decrease in the fluid's pressure
An increase in pressure at all points in the fluid
