Which statement best describes the movement of atoms in a gas?
Which statement best describes the atoms in a gas? They move freely in all directions. Sample Response: The windsurfer, his board, and the air and water around him are all made of matter. That matter is made up of very small particles called atoms, which cannot be divided.
What describes the motion of atoms in a gas?
In gases the particles move rapidly in all directions, frequently colliding with each other and the side of the container. With an increase in temperature, the particles gain kinetic energy and move faster. In liquids, particles are quite close together and move with random motion throughout the container.
Which statement best describes a gas?
A gas is a state of matter in, which atoms remains in a constant motion, they do not stick together. They are free and can move in all directions. The gas molecules expands to fill the available space.
What best describes the shape and volume of a gas?
gas: Has no definite shape or volume. change of state: When matter is converted from one of the three states (example: solid, liquid, or gas) to another state.
Which of the following best describes the liquid?
A liquid has a definite volume but not a definite shape. A liquid expands to fill the shape and volume of its container. A liquid cannot flow.
What are the properties of solid and liquids?
Gases
| Characteristic | Solid | Liquid |
|---|---|---|
| shape | definite | indefinite |
| volume | definite | definite |
| relative intermolecular interaction strength | strong | moderate |
| relative particle positions | in contact and fixed in place | in contact but not fixed |
What are the main characteristics of solids?
General Characteristics of Solid State
- Definite mass, volume, and shape.
- Short Intermolecular distance.
- Strong Intermolecular Forces.
- The constituent particles remain fixed at their positions and can only oscillate about their mean positions.
- Solids are incompressible and rigid.
- High Density.
What is liquid class 9th?
Liquid: Matters which have fixed volume but indefinite shape are called liquids. For example – milk, water, petrol, kerosene, alcohol, oil, etc. Since liquid can flow, it is also called fluid.
What is a matter Class 9?
Matter- Matter is anything which occupies space and has mass is called matter. Air and water, sugar and sand, hydrogen and oxygen etc. Matter is made up of very small tiny particles. Particles of matter have space between them they attract each other. 2.
