Alpha particles are relatively heave and can be stopped by a sheet of paper.
I think D, not sure though!
Answer:
At low temperatures than melting point the substance remain as a solid. Then from melting point temperature to boiling point the substance will remain as a liquid. This is the temperature at which a liquid become a gas. When we increase the temperature of a liquid it will become gas at its boiling point.
Explanation:
Firstly, colligative properties focus on the NUMBER of particles in the ratio of the solute to the solvent. Finally, examples of such are: the decreasing of vapor pressure, the increasing of one's material to its boiling point, the decreasing again of one's material to its freezing point, and osmotic pressure.
