When this happens, the water does not appear to be boiling, but just a slight disturbance to the water, which can occur when touching or picking up the cup, can cause an eruption of boiling water. This can lead to skin burns.32. What does the second paragraph mainly talk about? A. H...

Heavier halogens have more electrons in their valence shells. This can make Van der Waals forces stronger, slightly increasing boiling point.
How does the entropy of a system change for the following process: A vapor condenses to a liquid. Compare the entropy change when vapor forms over pure solvent and over a solution at their boiling points. What would be the effect of either increasing or decreasing the pressure over a liquid...
Liquids having less boiling points have high vapor pressure, so does that mean increasing altitude vapor increases as boiling point decreases with height? Boiling and freezing occur when water is subjected to: (a) decreased temperatures. (b) ...
Does photosynthesis take place at night?Photosynthesis doesn't occur at night. When there is no photosynthesis, there is a net release of carbon dioxide and a net uptake of oxygen. If there is enough light during the day, then: the rate of photosynthesis is higher than the rate of ...
Why does rice get slimy? When rice is shipped, grains jostle around and rub against one another; some of the outer starch scratches off. When the now starch-coated rice hits the boiling water,the starch blooms and gets sticky. How do you store a big bag of rice?
Most electric kettles should include an easy on-off controller, but some have added features such as giving you the capability to adjust the boiling water temperature so you are able to create perfect spicy tea, not merely the typical beverage that is hot. For example, if you’re creating ...
(300 meters) increase in altitude, above sea level. For those dishes where there is some direct relationship to the boiling point of water, for example in cooking sugar to make syrups or candies, the temperature at which events occur happen sooner because water boils at a lower temperature. ...
Be ready for the next time when a friend begins to share some of her complaints. Perhaps interject something like: “I know that Joe isn’t perfect, but what is something that he does really well?” A true friend will support your marriage and help pull you out of the pit of self-...
