The mathematical modelling of free and moving boundary problems are an important topic in engineering, industry, technology and theoretical sciences. These models allow us to make calculations ...

People not in the refrigeration business often think that refrigeration equipment produces cold air; in fact, the equipment is actually removing heat from air and leaving what’s left — the cold. When ...

Water can exist in three phases: a frozen solid, a liquid, and a gas. When heat is applied to a frozen solid, it becomes a liquid. When applied to the liquid, it becomes vapor. This elementary ...

Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. Hi, everyone. This is Mrs Bhardwaj and it's science time. Are you ready for your investigation? What ...

Heat transfer between objects a few molecules apart is 100x higher than predicted, confirmed by new data. Cause unknown but key for nanoscale temperature control. (Nanowerk News) More heat is ...

Radiation is the transfer of heat energy from a region of high temperature to a region of low temperature by infrared radiation. Unlike conduction and convection, radiation takes place without the ...
