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? Fog surround icebergs due to advection fog.

Banana related information My friend Petal peels her bananas from the bottom. Well‚ it’s the top‚ actually‚ since bananas grow upside down. Come to think of it‚ that’s not quite right either—bananas grow the way they grow‚ which should be right-side up by definition‚ even if we think of them as upside down. So let me start over. Petal peels her bananas from the end without the stem. I mentioned as much at the lunch table last week and triggered a firestorm of debate that has put several

from the mainstream media‚ the biggest perceived benefit of vaping was the relative safety when compared with smoking. As E-cigs and vaping grew in popularity‚ many municipalities started enacting draconian anti-vaping laws. These laws treated the vapor produced by E-cigs and vaping as if they were just as dangerous as second hand smoke produced by cigarettes. Lawmakers continually cited faulty studies‚ citing “the dangers of formaldehyde produced by vaping” as a justification for their bans. The
