If the ideal gas constant has a volume of 0.0821 what are the units?
The ideal gas constant ( R ) with a value of 0.0821 has units of liters·atmospheres per mole·kelvin (L·atm/(mol·K)). This means it describes how much volume one mole of an ideal gas occupies at standard temperature and pressure. The units reflect the relationship between pressure, volume, temperature, and the amount of substance in the ideal gas law equation, ( PV = nRT ).
What variables and units are used to describe a gas?
Pressure, volume and temperature, and moles of gas are the four principal variables to describe a gas (for example, see related questions on Ideal Gas Law and others). The standard units are: Pressure: atmospheres (atm) Volume: liters (L) Temperature: Kelvin (K) Number of moles are measure in, well, moles.
What are the standard units of length mass volume and temperature in the metric system?
Length: metreMass: kilogram Volume: litre temperature: Kelvin.
What is the pressure at stp in bar units?
The pressure at standard temperature and pressure (STP) is 1 bar.
What is the common unit for solubility?
grams of solute per 100 milliliters of solution
What units are used in gay lussac's law?
Gay-Lussac's Law relates the pressure and temperature of a gas at constant volume. The units for pressure are typically expressed in atmospheres (atm), pascals (Pa), or millimeters of mercury (mmHg), while temperature is measured in Kelvin (K). The law states that the pressure of a gas is directly proportional to its absolute temperature. Thus, as temperature increases, pressure increases, provided the volume remains constant.
What is the meaning of scale division?
The scale divisions indicate the value of measuring units of volume, temperature, pressure, etc.
What types of measurements are useful when working with gases-?
You must know Pressure, and Volume , and Temperature when making accurate measurements of Gas quantity. Most of the world measures gas pressure in KiloPascal, volume in Cubic Metre, and temperature in degrees Centigrade . It is essential to use all Metric units Or all Imperial units, but Imperial units are only used by the USA now. The volume of all gases, changes with change of pressure and also with change of temperature. That is why you must measure all 3 units referred to .

What happens to the pressure when volume increases or decreases and temperature stays constant?
When the temperature is increased, the volume of a container gets larger, and vice versa. This can be found by examining one of the fundamental laws of gasses, the combined gas law. It states that the product of pressure and volume, divided by temperature yields a constant value: pV/T=k Where k is a constant with units of energy/temperature. Thus, in order for k to remain constant, temperature and volume must be varied inversely to one another.
What are common units for volume?
ml litre
What are three measurements that are helpful when working with a gas?
Temperature, Pressure, # of moles, volume of container. If you know any three of those you can find the remaning by equation PV=nRT, where P=pressure in atmospheric units, V=volume in liters, n=number of moles of the gas, R=universal gas constant (which, in this formula, is equivalent to .08206), and T=temperature in Kelvins (not centigrade, but kelvins).
The product of pressure and volume has the same si base units as?
The product of pressure and volume has the same SI base units as energy or work, which is measured in joules (J). This is due to the definition of pressure (P) as force per unit area (N/m^2) and volume (V) as cubic meters (m^3), where the units of pressure times volume results in joules (J).
What are the standard units of length mass volume and temperature in the metric system?
Length: metreMass: kilogram Volume: litre temperature: Kelvin.
What are the common units for xpressing the volume of liquids?
liters
What is the pressure at stp in bar units?
The pressure at standard temperature and pressure (STP) is 1 bar.
