In contradiction to solids, gases never have a definite volume. 全部否定句,译文:与固体不同,气体从来没有固定的体积。 A、正确 B、错误
True or false? Gases have no definite volume.Gases:One of the properties of gases is that they react with the external pressure, When the external or applied pressure is increased, the distance from each other decreases causing the gaseous system to deviate more from the ideal conditions. This...
they regain their original shape which implies that rubbers have a definite shape that satisfies the condition that all solids have a definite shape, volume and don't follow like liquids or do not lose their shape under a force or do not take the shape of the container...
A. Have a definite volume but NOT a definite shape 1. Particles are free to move around 2. Liquid is also called a fluid - substance that flows II. Liquids B. Viscosity - resistance of a liquid to flowing 1. High viscosity: moves s l o w l y Ex. Honey, molasses 2. Low viscosit...
Solids have a definite shape and volume. Liquids have a definite volume but take the shape if their container. Gases take the shape and volume of their container, Air is a mixture of different gases that have no color. While air is invisible, it is an example of matter, thus has mass ...
as a substance cools, the particles tend to move more slowly, and average kinetic energy decreases. particle diagrams postulates for a gas atoms are spread apartgases have no definite shape or volumegas particles are movinga vacuum is an empty space with no particles and no pressure vapor ...
Gases have three characteristic properties and they are easy to compress. The characteristics of gases are described fully in terms of four parameters or measurable properties, Since gases occupy the entire space available to them.

have no definite volume or shape (compressible). b. assume the shape and volume of their containers. c. there is much space between molecules (very low density). What is pressure? Pressure is a force per unit area. For gases, pressure comes from the pounding of molecules against each ...
