Learn about solid, liquids and gases with these interactive learning resources for KS2 Science students aged 7-11 from BBC Bitesize.

Matter is the "stuff" that makes up the universe. Everything that has mass is matter. In normal everyday life we come across matter in three states, solid, liquid and gas.

In gases the particles are much further apart than in solids or liquids because theattraction between the particles is small. Thismakes gas even more mobile and fluid thanliquids. There's a lot of ...

Water is the only substance on Earth that occurs naturally as a solid, liquid, and gas. But scientists can artificially transform substances that occur naturally in only one or two forms of matter ...

This Simple Demo Explains Solid, Liquid, and Gas. What's going on with H 2 O molecules when they change from ice to water to vapor? By Jay Bennett Published: Aug 16, 2016 9:30 AM EDT.

i.e. αv = 1/T for ideal gas At 0 °C, αv = 3.7 × 10 -3 K –1 , which is much larger than that for solids and liquids. There is relation between the coefficient of volume expansion and ...

Draw or project the illustration Solid, Liquid, and Gas. Have students use the projected illustration as a reference as they draw a model of solids, liquids, and gases on their activity sheet. Point ...

The four fundamental states of matter are solid, liquid, gas and plasma, but there others, such as Bose-Einstein condensates and time crystals, that are man-made.

Like a liquid, a gas will take the shape of any container it is in and has no fixed shape. But unlike liquids and solids, gases can also change their size or volume.
