Mrc Years 56 States Of Matter Quiz Set 1

There are four fundamental states of matter: Solid, Liquid, Gas, and Plasma. Solids are characterized by their firm and stable structure, not flowing like liquids or gases.

Gas is a state of matter that has no fixed shape or volume, allowing it to be compressed tightly or expanded to fill any container. Solids have a fixed shape and volume, while liquids have a fixed volume but take the shape of their container. Plasma is a state of matter where ions and electrons become free due to high energy.

The process of liquefaction by heating is known as melting, where a solid substance transforms into a liquid form. Boiling is the process of turning a liquid into a gas through heating, freezing is the process of turning a liquid into a solid through cooling, and condensing is the process of turning a gas into a liquid through cooling.

The melting point of a solid substance is the temperature at which it changes from a solid to a liquid state.

A phase change is the transition of matter from one state to another, such as from solid to liquid or gas. While 'State Transition' sounds similar, it is a more general term. 'Matter Shift' is not a scientific term. 'Solidification' specifically refers to the process of a substance becoming solid.

Sublimation is the process by which a substance transitions directly from the solid phase to the gas phase without passing through the liquid phase. It involves the solid molecules gaining enough energy to break free from the solid phase and enter the gas phase.

The question is referring to the state of matter that has a definite volume but no fixed shape, which is a characteristic of liquids. Solids have both definite volume and shape, gases have neither definite volume nor shape, and plasmas do not have definite volume or shape either.

Plasma is the fourth state of matter where gas becomes ionized due to high temperature or other energy input, resulting in positive ions and free electrons.

Deposition is the phase transition process in which a gas transforms directly into a solid without passing through the liquid phase. Evaporation is the process in which a liquid turns into a gas, while condensation is the reverse process. Sublimation is the phase transition in which a solid turns directly into a gas.

When a liquid turns into a solid by lowering its temperature below the freezing point, it is known as freezing. Melting is the opposite of freezing, while vaporization and condensation are phase transitions involving gas and liquid states.

Vaporization is the phase transition from liquid to vapor, which includes both evaporation (gradual process) and boiling (rapid process). Condensation is the opposite process, where vapor turns into liquid. Sublimation is the direct transition from solid to vapor without passing through the liquid phase. Melting is the phase transition from solid to liquid, not liquid to vapor.

Condensation is the process where a gas or vapor transforms into a liquid. Evaporation is the opposite process where a liquid turns into a gas. Sublimation is the direct conversion of a solid into a gas without passing through the liquid state. Deposition is the reverse process of sublimation, where a gas transforms directly into a solid.
