What happens to convection currents when liquid or gas is no longer heated? Which one of the following best describes sublimation? A)The movement of gaseous particles so that they fill the space that they occupy B)A solid forming a vapour on heating and reforming as a solid on colling...
Since billions of trillions of particles constitute a gas, its kinetic energy is measured as an average of the kinetic energy of the particles that...
So, if you ever find yourself in sweltering heat or sub-zero temperatures, your iPhone might struggle to cope. Continued exposure to heat can affect your iPhone’s battery over time. When it’s too hot, the battery can’t store energy efficiently, so you’ll start to notice a lag in ...

What is the analogous thing that happens to particles with rest mass (e.g. neutrinos)? When you decrease the energy of a particle with rest mass, its speed decreases. (Or looked at another way, if the thing emitting it is moving away, then the particle is traveling slo...
When the water dispenser has not been used for a long time If the dispenser has not been used recently the first glass of water may not be as cool. (The residual water in the water pipe may become hot.) Dispensers may need approximately 2 to 3 hours to chill ...

range (41 to 135 degrees Fahrenheit) is prone to rapid bacteria growth which can cause foodborne illness. This is where a blast chiller comes in. A blast chiller brings food through the danger zone as quickly as possible, avoiding the potential for bacteria growth when you are cooling hot ...
etc. The “Google Glass”, a wearable computer with an optical head-mounted display similar in general appearance to a pair of eyeglasses, includes a tiny glass LCD display panel, although the main frame, because of durability and weight considerations, is actually made of a durable plastic an...
This process is essential to kickstart the water cycle, a continuous movement of water on, above and below the surface of the Earth. Evaporation occurs when heat from the sun causes water from oceans, rivers, lakes and other sources to turn into water vapor. Condensation happens when water ...
