The phenomenon by which molecules in liquid state undergo a spontaneous transition to the gaseous phase at any temperature below its boiling point is called evaporation. For example, the gradual drying of damp clothes is caused by the evaporation of water to water vapour.

By applying pressure, the interparticle spaces between particles of matter decreases. Thus, by applying pressure and reducing temperature we can convert a solid to liquid and a liquid to gas. Flowchart for inter-conversion of the three states of matter

Effect of change of temperature on state of matter On increasing temperature, the kinetic energy of the particles of the matter increases and they begin to vibrate with a higher energy. Therefore, the interparticle force of attraction between the particles reduces and particles get detached from their position and begin to move freely. As a result,… Continue reading Can Matter Change Its State?

When the particles of matter intermix on their own with each other, the phenomenon is called diffusion. For example, spreading of ink in water. During diffusion, the particles occupy the interparticle spaces. The rate of diffusion increases with increase in the temperature, due to increase in kinetic energy of the particles.

Matter Matter is anything that has mass and occupies space. Everything that we can touch, see, hear, taste and also smell is matter. It is made up of really tiny particles which cannot be seen through the eye. The particles of which the matter is comprised influence its state and properties (physical and chemical). 1. Particles of matter have… Continue reading Characteristics of Particles of Matter

A physical property is that aspect of the matter that can be observed or measured without changing its nature or composition. It is independent of the amount of matter present. Physical properties include appearance, colour, odour, density, texture, melting point, boiling point, solubility, etc.

Matter In Our Surroundings:  Anything that has mass and takes up space is referred to as matter. hydrogen and oxygen, sugar and sand, air and water, etc. Small, minuscule particles make up matter. Due to the space between them, matter particles are attracted to one another. States of Matter Matter can be classified as solid,… Continue reading States of Matter
