State few characteristics of pressure.
Answers
Answer:
Sure! Here are some characteristics of pressure:
Pressure is a scalar quantity, meaning it has magnitude but no specific direction.
It is defined as force per unit area, with the SI unit of measurement being the pascal (Pa).
Pressure can be exerted by gases, liquids, and solids.
The pressure at a point in a fluid at rest is the same in all directions.
Pressure is proportional to the depth of a fluid, meaning that the deeper you go in a fluid, the greater the pressure.
Pressure can be positive or negative, depending on whether it is greater or less than atmospheric pressure.
Pressure can be measured using various instruments, such as manometers, barometers, and pressure gauges.
Changes in pressure can cause changes in the physical properties of matter, such as melting or boiling points.
Pressure plays a critical role in a wide range of phenomena, including weather systems, fluid dynamics, and industrial processes.
Answer:
.1. pressure is a scalar physical quantity (having magnitude but no direction ). 2.Pressure can be increased by either increasing the force or by decreasing the area or can oppositely be decreased by either decreasing the force or increasing the area. 3. Barometer is used to measure atmospheric pressure and nanometer is used to make measure pressure in laboratory.
