The molecules in hot water move faster than those in cold water. Hot water molecules bounce around and leave gaps. This makes hot water slightly less dense than cold water. So when you put the cold water on the bottom, the denser cold water stays there. But when you put the cold water...
All the gases exert pressure on the walls of the container. 1)Air is a mixture of gases. 2)All the gases are made up of tiny particles called molecules which move around quickly in all directions. 3)The fast moving gas molecules collide with one another and with the walls of the contai...
When they're in the nematic phase, liquid crystals are a bit like a liquid: their molecules can move around and shuffle past one another, but they all point in broadly the same direction. They're a bit like matches in a matchbox: you can shake them and move them about but they all ...
screens with ips technology use liquid crystal molecules that align parallel to the screen surface, allowing for wider viewing angles and better color accuracy. ips panels provide consistent colors and maintain image quality even when viewed from different angles, making them suitable for professional ...
It's what we call thelatent heat of vaporizationof water: it's the energy you have to supply to move the molecules in the water far enough apart to turn the boiling hot liquid into a hot gas. So why does steam hurt more? If 100°C boiling water hits your body, it cools down and...
Liquid crystals are special compounds containing molecules whose orientation can be changed by applying a voltage. This change in orientation changes the amount of light that can pass through the liquid crystal. Due to this change, the brightness of each sub-pixel can be changed, and the monitor...
they’re banging around the whole time. When you heat up the air the molecules move faster and faster. Indeed, the average random motion of a molecule is the heat; that’s what official science will tell you. So let’s suppose the molecules start moving faster and faster. What’s going...
a molecule gains energy from the hot side and instead of a long process via random collisions with other air molecules, it is likely to hit the cold side next and lose some of its energy.Also, the figures provided by thermal compound manufacturers who focus on computers are n...
it will begin to heat up extremely fast compared to a plastic bottle that restricts the energy transfer from the hot air to the liquid. These difference in the materials response to a change in temperature can be analyzed by comparing the thermal conductivity of plastic vs metal materials. Reus...
Close the lid and let it steep for 3 days, and your grass-clipping liquid fertilizer is ready to use. Depending on the size of the plant, apply this solution from half a cup to one quart for those growing in pots. Learn about this technique in detail here. 7. Add a Grass Clipping ...
