What happens when the thermal energy of a substance increases? What happens to thermal energy when the number of particles increases? What happens to the atoms and molecules in a substance as its temperature increases? What happens when an amorphous solid is heated? What happens when an interstel...
Rain is defined as water droplets greater than .5 mm in diameter. Rain will occur if the temperature is above 32°F. Freezing rain occurs when water falls to the earth as rain and moves through a thin layer of freezing air before reaching the ground. Most precipitation falls as rain. Dri...
Inmy labat the University of Colorado at Boulder, I study small-scale laboratory avalanches. We use a technique calledphotoelasticityand create thin avalanches to revealwhat's going on inside the avalanche. We track photoelastic particles with a high-speed camera and can observe that particles bounc...
Matter is a substance made up of various types of particles that occupies physical space and has inertia. According to the principles of modern physics, the various types of particles each have a specific mass and size. The most familiar examples of material particles are theelectron, the proton...
That means the droplets remain liquid even when temperatures drop below the typical freezing point of water, which is 32 degrees. "Supercooling happens when water droplets are exceptionally pure and lack small particles, such as dust, fungal spores, pollen, or bacteria, around which ice crystals...
Then, quite literally, there's a twist. Because of your previous momentum and the number of other particles rushing toward the drain at the same time, chances are that you're going to be pushed off to one side of the point of suction when you arrive. That deflection sets you on a ...
October 16 and 17 brings the full Hunter's Moon, and it's going to be a good one. The closest full supermoon of the year, it also bears important seasonal reminders.
To understand this, it helps to look into where the measurement comes from. Before the creation of thermometers, smiths, potters, and glassblowers depended on the color of the glowing material to track progress. Consider what happens when an iron bar is heated to a soaring temperature. First,...
Is the process of liquid water being converted to ice endothermic or exothermic? What happens when a solid is dissolved into a liquid? What is enthalpy of steam? Which of the following releases the greatest amount of energy? a. steam condensing to water b. water freezing to ice c. ice me...
It is wise to protect yourself when in areas with dense air pollution. Getting a high-quality mask before you go will potentially save you from paying a higher price for one when you arrive. The KN95 is good quality and will filter out 95% of all particles in the air. View on Amazon...
