What is the unit of volume times pressure?
Pressure–volume work (or PV work) occurs when the volume V of a system changes. PV work is often measured in units of litre-atmospheres where 1L·atm = 101.325J.
What is the unit for specific volume?
The standard unit of specific volume is cubic meters per kilogram (m3/kg), but other units include ft3/lb, ft3/slug, or mL/g.
What do you get when you multiply pressure by volume?
When you take any point on the curve and multiply the pressure value by the volume value the product equals the constant. This graph is consistent with Boyle’s law.
What are the units for PV nRT?
The units used in the ideal gas equation that PV = nRT are: P is pressure measured in Pascals. V is the volume measured in m. n is the number of moles.
What is the T in PV nRT?
PV = nRT is an equation used in chemistry called the ideal gas law equation. P = pressure of the gas. V = volume of the gas. n = number of moles of the gas. T = Temperature expressed in units of Kelvin.
What is the pressure unit?
Unit of pressure: pascal (Pa) Pressure is the amount of force applied perpendicular to the surface of an object per unit area and the for it is p (or P). The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m2, or kg·m−1·s−2).
How do you solve specific volume?
Formula for Specific Volume Specific volume equals volume divided by mass. Typically, volume is measured in cubic meters (m3), and mass is measured in kilograms. Specific volume is then calculated as volume divided by mass.
What is specific volume example?
Specific Volume and Specific Gravity For example, if substance A has a specific volume of 0.358 cm3/g and substance B has a specific volume of 0.374 cm3/g, taking the inverse of each value will yield the density. Thus, the density of A is 2.79 g/cm3 and the density of B is 2.67 g/cm3.
How do you solve for pressure and volume?
First, let’s review the ideal gas law, PV = nRT. In this equation, ‘P’ is the pressure in atmospheres, ‘V’ is the volume in liters, ‘n’ is the number of particles in moles, ‘T’ is the temperature in Kelvin and ‘R’ is the ideal gas constant (0.0821 liter atmospheres per moles Kelvin).
