and got attracted to the ruler. 1. Were all three substances affected equally? - No only friction because rubbing was only done. 2. What explanations can you offer for why this happened? - I suggest that this happened because when you rub two things hardly obviously there is friction going on. Also I tried it with my hair even though that wasn’t told but the same results happened. The rest of the substances did not occur because they were not instructed to apply. B. What combinations

compounds. At any given temperature‚ a certain number of molecules of a substance in the liquid state have sufficient energy to escape from the surface to create a vapor pressure. This tendency becomes greater as the kinetic energy of the molecules is increased by raising the temperature. When a liquid is heated to a temperature at which the vapor pressure equals that of the surrounding atmosphere‚ the liquid boils‚ and this temperature is known as the boiling point. The boiling point of a pure substance

more rapid on clear night than cloudy nights since there is no clouds to emit back to the surface. Hence the phrase “clear moon‚ frost soon”. The cool surface is then mixed with air above it‚ which will eventually cool to the dew point and water vapor will appear on the cooled surfaces. If the temperature continues to fall in the freezing range then the dew will freeze and frost will form. 2. Explain why icebergs are frequently surrounded by fog?
