# Which equation agrees with the ideal gas law?

## What does the ideal gas law predict?

In physics, you can use the ideal gas law to predict the pressure of an ideal gas if you know how much gas you have, its temperature, and the volume you’ve enclosed it in. For an ideal gas (at constant volume), pressure is directly proportional to temperature.

## What is the temperature of 0.80 mol of a gas stored in a 275 ml cylinder at 175 kPa?

Therefore, the temperature is around 7.24 K .

## What R is used in PV nRT?

1 Answer. The units of the universal gas constant R is derived from equation PV=nRT . It stands for Regnault.25 мая 2014 г.

## What is represented in the ideal gas law?

The Ideal Gas Law is a simple equation demonstrating the relationship between temperature, pressure, and volume for gases. … P is the pressure, V is the volume, N is the number of moles of gas, R is the universal gas constant, and T is the absolute temperature.

## How do you calculate ideal gas law?

The ideal gas equation is given by PV=nRT P V = n R T .

## What is the molar volume of a gas at standard temperature and pressure?

Standard temperature and pressure (STP) is defined as 0oC (273.15K) and 1atm pressure. The molar volume of a gas is the volume of one mole of a gas at STP. At STP, one mole (6.02×1023 representative particles) of any gas occupies a volume of 22.4L (figure below). Figure 10.13.

## What does N mean in PV NRT?

A physical law describing the relationship of the measurable properties of an ideal gas, where P (pressure) × V (volume) = n (number of moles) × R (the gas constant) × T (temperature in Kelvin). It is derived from a combination of the gas laws of Boyle, Charles, and Avogadro.

## What is r equal to?

The value of the gas constant ‘R’ depends on the units used for pressure, volume and temperature. R = 0.0821 liter·atm/mol·K. R = 8.3145 J/mol·K. R = 8.2057 m3·atm/mol·K.

## What is the value of N in PV NRT?

We can use the ideal gas equation to calculate the volume of 1 mole of an ideal gas at 0°C and 1 atmosphere pressure. First, we have to get the units right. We know that n = 1, because we are trying to calculate the volume of 1 mole of gas. And, finally, R = 8.31441 J K-1 mol-1.

## Why is it called ideal gas law?

An ideal gas is a gas that conforms, in physical behaviour, to a particular, idealized relation between pressure, volume, and temperature called the ideal gas law. … A gas does not obey the equation when conditions are such that the gas, or any of the component gases in a mixture, is near its condensation point.

## What does Boyles law mean?

This empirical relation, formulated by the physicist Robert Boyle in 1662, states that the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature; i.e., in equation form, pv = k, a constant. …
