Matter can be defined as something that
Matter is defined as something that which occupies space and possesses rest mass, especially as distinct from energy and exists in all the three states.
Ice is the _______ form of water.
Ice is the solid form of water.
The forces of attraction between molecules is greatest in the _________ state.
In solids, the particles are tightly packed in a rigid pattern.
The state of matter which has no fixed shape but has definite volume is the
Matter in the liquid state has no fixed shape but has definite volume.
Which of the following is true of the molecules of gases?
The molecules of a gas move freely.
Ice melts when energy in the form of________ is supplied.
By the absorption of heat, ice melts to form water.
In a bar of magnet the molecules are held by
Bar magnet is a solid. In a solid, its molecules are held by strong forces of attraction.
The process of changing water to water vapor is called
When water is heated, it changes to water vapor. The process is called evaporation.
A compound is formed when
A compound is formed when two or more kinds of atoms combine.
Matter is made up tiny particles called
Matter is made up of tiny particles called atoms.
Which of the following determines the state of matter?
The state in which matter exists depends on how the molecules in it are packed.
The intermolecular space between molecules is maximum in a
In a gas, the molecules are far away from each other.
When a solid is heated, it melts to form
Solids melt to form liquids.
Which of these processes involves change of state from the liquid to gaseous state?
When water is heated, it evaporates to form water vapor.
Substance 'P' does not have a fixed volume. It occupies the total space of the container and it can be compressed. What is 'P' likely to be?
Gases have no strong bonds between the atoms. They can be compressed.
Water present in container 'P' is transferred to container 'Q' as shown in the figure. Which of the following will undergo a change because of the transfer?
Liquids take the shape of the container, so the shape changes.
When we heat a substance in solid form, it becomes liquid and then into gas. This shows that by heating, the space occupied by the substance generally:
By heating the molecules moves apart, hence they occupy more space.
In the table given below, states of matter, their properties and examples are represented by letters W, X, Y, Z.
Q. Carbon dioxide can be placed in the place of letter________.
Carbon dioxide is an example of gaseous state and so can be placed under z.
The picture shows the process of _________.
The picture shows the process of melting.
The force of attraction between molecules is the strongest in
Figure A shows the strongest forces of attraction between the molecules of a solid.
