So that you do not overcook the veggies. Works with other veggies the same way.
Depending on the vegetables, you can steam them or Blanche them. (Where you put vegetables in boiling water, then put them in ice cold water)
If you do not have a steamer there are a few easy ways you can steam broccoli. Broccoli can be steamed in a covered pan with a few inches of water. It can also be steamed with water in the microwave.
HI To remove salt from water, boil the water and the steam from the boiling water will be free of salt. Salt is heavier than air so it cant follow the steam. Put a thick piece of aluminium above the steam at a thirty degree angle, the steam will condensate on the plate and flow down the slope into a container sitting beside the boiling water. Not only will it be free of salt it will be almost germ free.
At 60̊ C water is very hot. Too hot to put your hand in, but it's still water. It isn't steam/water vapor/boiling.
Steam carries more energy than boiling water. When water is at its boiling point, it requires additional energy to boost it into a gaseous state. When the steam comes in contact with a cooler object and condense back to a liquid, it releases that energy as heat. If that object is human skin, that heat will cause a burn. - - - - - It would be very rare to have steam with the same temperature as boiling liquid water. The only way to keep water liquid past 100 degrees C is to put it under pressure. By contrast, once you have formed steam you can raise it to just about any temperature you want - there are many industrial processes that require steam at 600 degrees F. Hence, at least part of the reason burns from steam are more severe than burns from boiling water, is the steam is hotter.
Water can be distilled out of Coca-Cola by boiling it; the steam can be condensed into distilled water, leaving behind the syrup (the carbonation will be lost).
It is commonplace to put salt in water when boiling most foods. The reason why you put salt in with boiling water and vegetables is to help them retain moisture.
because the hot water in the can mix causing steam filling the can with gas. that puts too much pressure on the can and it implodes to get rid of the gas inside
The easiest way is in the microwave. In a microwave-safe dish (that has a top) a splash of water in the bottom and your micro can help you with the timing. You can also put the broccoli in boiling water and boil for about 15 minutes or until it is as tender as you like. Steamed broccoli is prepared by placing the broccoli on a steaming tray over boiling water. Cover with a lid and steam until it's as tender as you want it to be.
You put them in the water after the it is boiling not before

if you don't then gasses and steam build up inside and it explodes.
