Besides particles like sterile neutrinos, axions and weakly interacting massive particles (WIMPs), a leading candidate for ...

in which particles of light could free electrons from atoms in the material they strike. “The finding of evaporation caused by light instead of heat provides new disruptive knowledge of light ...

Students will be able to develop and explain a particle-level model to describe their observations of water dissolving salt, the water evaporating, and the salt crystals re-forming. Dissolving a solid ...

In evaporation, particles leave a liquid from its surface only. In boiling, bubbles of gas form throughout the liquid. They rise to the surface and escape to the surroundings, forming a gas.

Learn how a trio of scientists do the math, based on a Stephen Hawking theory, and even ask how long it would take for a ...

Repeat this for your other water molecule. Position your water molecules so that opposite charges are near each other. Have students design a test to compare the rate of evaporation between water and ...

Various nonspherical polystyrene (PS) particles were prepared by slow evaporation of toluene (used common good solvent) from homogeneous PS/hexadecane (HD)/toluene droplets dispersed in surfactant ...
