Why are high temperatures required in the synthesis of YBa2Cu3O7? Why does water have a higher boiling point compared to ethanol? Explain very briefly why the boiling point of H2O is higher than that of H2. Explain why the melting point and boiling point of alkali metals are low. ...
Why does oil not dissolve in water? Why does water have a high specific heat? Why is copper malleable? Why is density important to mineralogy? Why is the Antarctic Ice Sheet melting? Why isn't the Antarctic Ice Sheet melting? Why is diamond brittle, even though it is the hardest substanc...
Can you make ice cubes faster with hot water? Even with more ground to cover to freeze, the temperature of the hotter water can drop at a faster rate than the cooler water. So the next time you refill your ice cube tray, try using warmer water. You might have ice cubes to cool your...
In the same way, microwave cooking – which involves the heating of water within the food (to a depth of around 1 to 3 centimetres, rather than “from the middle” as is often claimed) – generally won’t get much hotter than 100°C, the boiling point of water. Hence these wond...

So, I wouldn’t drink water with 60 alcohol in it as ingesting it may pose life threatening health risks. On the other hand, in case you have no access to bottled water or can’t boil water, the Centers for Disease Control and Prevention (CDC) advise using a chemical disinfectant, ...
boiling of water, as it’s an integral part of cooking. You put water in a container, keep it on the stove, and cover it (for maximum utilization of heat energy). However, when the water starts to make noise and the cover begins to tremble, you know that the water has successfully ...
Oil is used in cooking to improve the transfer of heat so that food cooks more effectively, similarly it also has a higher boiling point than water and so allows food to be cooked hotter and aids with the browning process (often a vital part of unlocking flavour and improving texture). ...
In Nepal, he says, there’s an “increase of the monsoon season now. Snow is melting faster, the glaciers are melting faster, the water is running faster and routes that we normally could access before are no longer accessible. So we’re actually having to shorten the [travel] seasons to...
