The change in temperature of a body causes expansion or contraction of that body. Most of the substances expand on heating and contract on cooling. This is called thermal expansion. It has been ...

The distances between particles are smallest in the solid, they are larger in the liquid and larger again in the gas. The particles in gases and liquids move more freely than in solids, so their ...

Solids, liquids and gases. In a solid like this brick, the particles are regularly arranged touching their neighbours and move only by vibrating. This explains why solids have a fixed shape. In a ...

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. When you purchase through links on ...

Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. Hi, I'm Diana. Great to be with you today. Have you ever seen one of these? It's a hot air balloon.

In a recently published article in the leading physics journal "Nature Physics", a team of researchers with the participation of the University of Augsburg reports about unexpectedly universal ...

Reversible temperature tuning of electrical and thermal conductivities of materials is of interest for many applications, including seasonal regulation of building temperature, thermal storage and ...

TL;DR: Thermal paste and pads both have their merits for cooling hot-running components like CPUs and GPUs. While quality thermal paste can effectively fill air gaps for optimal heat transfer when ...

Students are introduced to the idea that matter is composed of atoms and molecules that are attracted to each other and in constant motion. Students explore the attractions and motion of atoms and ...
