What Is Matter Class 9 Answer? Answer: Anything that occupies space and has mass is called matter. Matter can exist in three physical states—solid, liquid, and gaseous. Chair and almond are forms of matter in the solid state. What is matter Ka answer? Matter is a substance that has inertia and occupies physical space. According
Which Occupies The Most Volume At STP? Ar (Argon) is the gas that occupies the highest volume at STP. Which of the following occupies more volume for the same number of particles? Gases occupy more volume than solids and liquids for the same number of particles because of less inter-molecular force of attraction and more
Can Natural Gas Get Into Food? And what’s worse? Natural gas and propane actually cling to your food. So we eat it, when our food is cooked by gas. Can carbon monoxide be absorbed into food? Meat treated with CO is safe to eat. CO is only hazardous if you breathe it, but once it
Why Solid Matter Has Definite Shape And Volume But Gas Does Not? Solution : (a) Solids have definite shape and definite volume because the molecules in solid are closely packed and in fixed positions. … (c) Gases do not have a definite shape or volume because the molecules in gases are very loosely packed, they
Why Are Particles In A Liquid More Closely Packed Than Particles In A Gas? The average speed of particles in a liquid is much slower than the average speed of particles in a gas. The particles of a liquid are more closely packed than those of a gas. Therefore, attractions between the particles in a
Why A Gas Has No Definite Shape Or Volume? Gases do not have a definite shape or volume because the molecules in gases are very loosely packed, they have large intermolecular spaces and hence they move around. The force of attraction between molecules is also very less, as a result gases acquire any shape or
Why A Crystal Is Incompressible? Particles in the plasma move randomly, but particles in a solid vibrate in one place. Which best explains why a crystal is incompressible? Its molecules remain in position without vibrating. The molecules of a crystal behave like those of a gas. Why are plasmas good conductors of electricity? There is
Which Period Has Only Gases? A period 1 element is an element in the first period (row) of the periodic table. … It means that elements in the same group have similar properties. The first period has less elements than any other periods in the periodic table. There are only two elements in the first
Why Is Argon Used Instead Of Air In The Light Bulb? Did you know that incandescent light bulbs are filled with inert gases Why is argon or nitrogen filled in electric bulb instead of air? Main reason why electric bulb is filled with nitrogen or argon instead of air is that the bulb contains closed
Which Noble Gases Are Not Reactive? Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds. Are noble gases very
