Charles’s law is a gas law that states that for a fixed amount of an ideal gas kept at a fixed pressure, the volume and temperature are directly proportional. This means that if the temperature of a gas is increased, the volume will also increase, and vice versa.
Charles’s law is based on the kinetic theory of gases, which states that all matter is
made up of tiny particles that are constantly in motion. The faster the particles move, the higher the temperature. When the temperature of a gas is increased, the particles move faster and have more energy. This causes them to spread out and take up more space, which is why the volume of the gas increases.Charles’s law is a very important law of physics, and it is used in many different applications. For example, it is used to design refrigerators and air conditioners, which work by removing heat from a gas and causing it to contract. It is also used to design engines, which work by burning fuel to create heat that causes gases to expand.
The other options are incorrect because they do not describe the state of matter that Charles’s law is based on. Option A, solid, is incorrect because solids do not have a constant volume. The volume of a solid can change depending on the pressure and temperature. Option B, liquid, is incorrect because liquids do not have a constant volume either. The volume of a liquid can change depending on the pressure and temperature. Option D, none of the above, is incorrect because Charles’s law is based on gases.
