Properties of gases class 11

Gasses do not possess any definite volume or shape. They totally fill all the space accessible to them. The characteristic or properties of gases to fill the available volume within a container is the result of the freedom that gas particles have to move everywhere in the accessible space. Define thermal energy and how it determines the state of matter.

Discuss the gaseous state , its properties and the gas law.

Here we discuss about the volume, density, shape, compressibility, suppression, random motion and. Shear stress can change the shape of a solid keeping its volume constant. You should know that a thorough concept of Class and Class Physics to score better marks in the various entrance exam.

With a better concept on the latest syllabus, you can secure good marks. We provide solutions for questions given in Class Physics text-book as per CBSE Board guidelines from the latest NCERT book for Class Physics.

Introduction Ex 10. Streamline flow Ex 10. The gaseous state is the simplest of all states of matter, but only gases in the periodic table behave as gases under standard temperature and pressure conditions (STP i.e. atm. and 273K).

These gases are called pure gases. It explains to the students that gas consists of fast-moving particles, namely, atoms and molecules. Kinetic theory explains the behaviour of gases based on the idea that the gas consists of rapidly moving atoms or molecules. There are various chemical properties of inert gases that are mentioned below: 1) Characteristics of noble gases are odorless, non-flammable, colorless, and monoatomic gas with low chemical reactivity. All the noble gases conduct electricity and fluorescence which can be needed in many conditions to maintain a constant and safe environment.

Kinetic theory of gases proves the correlation between the macroscopic and microscopic characteristics of gases in a closed container. It establishes the connection between temperature, pressure and volume of gases with its molecular speed and kinetic energy. The triple points of neon and carbon dioxide are 24. Properties of gases. Estimate the fraction of molecular volume to the actual volume occupied by oxygen gas at STP.

Answer: Diameter of an oxygen molecule, d = A = x -m. Consider one mole of oxygen gas at STP, which contain total NA = 6. Gases fill their container completely.

The gases has morer properties compared to the other states of mater like. Specific Heat Capacity. Mathematicallycan be written as:-. Use the links below to see short video clips illustrating the different states of matter. Each clip opens in a new window.

Use the pause and play controls to stop the clip as needed. Changing solids to liquids. The specific heat capacity at constant volume (C v). The specific heat capacity at constant pressure (C r).

Solids, liquids and gases. Crude oil: A mixture of organic compounds (mainly hydrocarbons) Seawater: A mixture of various salt and water. Ink: A mixture of coloured dyes.

Gunpowder: A mixture of sulfur, potassium nitrate and carbon.
