Answer:
yes
Explanation:
molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance
A) The mixing of a substance with another substance due to the motion or movement of its particles is called diffusion.
b) Gaseous particles tend to undergo diffusion because they have kinetic energy.
Explanation:
When conducting a melting point experiment, if we were to heat a sample quickly. Large amount heat is provided instantly which would melt the crystals in the tube very quickly, even before the temperature of the thermometer reaches to that level. So the observes melting point would be much lower than the actual melting point when sample is heated slowly.
The electrons that are in the outermost electron shell, also known as the valence shell, have more energy then those in the inner electron shells, I hope this helps<3
