## What is pressure What does pressure depend on class 8?

Answer: Pressure is force unit per area. Pressure depends on two factors: The magnitude of force applied – the greater the force, the greater is its effect. The area over which the force is applied, i.e. the area of contact between the two objects.

## What is pressure explain with an example?

Pressure is defined as the physical force exerted on an object. The force applied is perpendicular to the surface of objects per unit area. The basic formula for pressure is F/A (Force per unit area). While you sip the beverage, you’re actually applying ‘Pressure’. …

What is pressure in BYJU’s?

It is the ratio of the force applied to the surface area over which the force is applied. We can define pressure as: The force applied perpendicular to the surface of an object per unit area over which that force is distributed.

What is Kilopascal unit of pressure?

Kilopascal (kPa), one thousand times the unit of pressure and stress in the metre-kilogram-second system (the International System of Units [SI]). One pascal is a pressure of one newton per square metre, or, in SI base units, one kilogram per metre per second squared.

### Which of the following is NOT unit of pressure?

Newton is not the unit of pressure. It is the unit of force. Atmosphere, torr and pascal (Pa) are the units of pressure.

### Is MM a pressure unit?

A millimetre of mercury is a manometric unit of pressure, formerly defined as the extra pressure generated by a column of mercury one millimetre high, and currently defined as exactly 133.322387415 pascals. It is denoted mmHg or mm Hg.

Is kg/m2 a unit of pressure?

A kilogram-force per centimetre square (kgf/cm2), often just kilogram per square centimetre (kg/cm2), or kilopond per centimetre square is a deprecated unit of pressure using metric units. It is not a part of the International System of Units (SI), the modern metric system. 1 kgf/cm2 equals 98.0665 kPa (kilopascals).

How many Pascals is 1 kg?

98066.5 pascals

## How do you convert Pascals to KG?

To convert a pascal measurement to a kilogram per square meter measurement, multiply the pressure by the conversion ratio. The pressure in kilograms per square meter is equal to the pascals multiplied by 0.101972.

## How do you calculate Pascals?

The SI unit of the pressure is the pascal with the formula sign Pa. 1 Pascal is equal to the pressure of 1 newton per square meter. 1 Pa = 1 N / m2 ≡ 1 kg / m · s2. = 760 mmHg = 29.92 inHg = 14.7 lb/in2.

How do you calculate Kilopascal?

kPa = kilo Pascal; mmHg = millimetres of mercury. Example of conversion: e.g. 200 mmHg = 200 × 0.133 = 26.6 kPa.

What are 3 things that we commonly measure in kPa?

Kilopascal Uses Even in the United States, kPa is often used in favor of pounds per square inch (PSI). The pascal, kilopascal, and gigapascal (GPa) are used to express tensile strength, compressive strength, Young’s modulus, and stiffness of materials.

### What is standard atomic pressure?

The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa; 1,013.25 mbar), which is equivalent to 760 mm Hg, 29.9212 inches Hg, or 14.696 psi. …

### What is difference between PSI and kPa?

The conversion ratio from psi to kPa can be determined as follows: 1 kPa = 1000 Pascals (Pa) 1 psi = 6894.76 Pascals (Pa) kPa value x 1000 Pa = psi value x 6894.76 Pa….kPa pressure related products.
