# Which statement can best be concluded from 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 a real life example of ideal gas law?

In Real Life

For example, if an engineer has to store 600g of oxygen in a container and that oxygen needs to be kept at a pressure of 1 atm and a temperature of 125 degrees Fahrenheit, the Ideal Gas Law is used to figure out what volume of a container needs to be built.

## What does R mean in ideal gas law?

universal gas constant

## How accurate is the ideal gas law?

The ideal gas law, naturally, is only accurate for gases under “ideal” type conditions — high temperature and low pressure. … That’s pretty far removed from “ideal gas” and it shows: equations based on ideal gas behavior, such as Boyle’s Law, routinely result in 10-20% error for accumulator performance.

## 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 units is pressure in the ideal gas law?

Pressure is measured in pascals ( Pa ) — sometimes expressed as newtons per square metre ( N⋅m-2 ). These mean exactly the same thing. Be careful if you are given pressures in kilopascals ( kPa ). For example, 150 kPa = 150 000 Pa .

## What is P in PV nRT?

In the formula P V = N R T {displaystyle PV=NRT,} : P is the pressure of the gas. In SI units, this is measured in Pascals, or Newtons of force per square meter of area. (“Standard atmospheric pressure at sea level” is about 101,000 Pascals, or 101 KiloPascals.

## What is a real life example of Charles Law?

Real Life Example: A real life example of Charles’s law is leaving a basketball out in the cold weather. When a basketball if left in a cold garage or outside during the cold months, it loses its air inside (or volume). This is showing, with constant pressure, if the temperature drops, the volume decreases also.

## How does Boyle’s law apply to everyday life?

You can observe a real-life application of Boyle’s Law when you fill your bike tires with air. When you pump air into a tire, the gas molecules inside the tire get compressed and packed closer together. This increases the pressure of the gas, and it starts to push against the walls of the tire.

## What is an ideal gas simple definition?

a gas composed of molecules on which no forces act except upon collision with one another and with the walls of the container in which the gas is enclosed; a gas that obeys the ideal gas law.
