It includes observations and conclusions that students are meant to make on their own. Evaporation occurs when molecules in a liquid gain enough energy that they overcome attractions from other ...

But if it is, it’s “totally new.” Normally, heat is what gets evaporation going, causing water molecules in the liquid to jostle more vigorously. That extra energy can break some of the ...

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 ...

The water cycle depends on the processes of evaporation and condensation. Evaporation happens when water molecules at the surface of a liquid move fast enough to break away from other water molecules ...

Evaporation is an endothermic process undertaken by all liquids. This physical state change occurs when surface molecules gain sufficient kinetic energy to overcome the enthalpy of vaporization.

Proton emission is a rare form of radioactive decay, in which the nucleus emits a proton to take a step towards stability,” ...

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.

such evaporation may be commonplace—even when black holes aren't around. In the 1970s the late British physicist Stephen Hawking began thinking about what happened to particles that experienced ...
