No, because oil has a higher boiling point.
Putting a lid on the pan makes the water boil quicker because the heat is trapped, less is escaping, so the water's temperature has more time to increase, so it gets more hot and boils faster.
in order to separate soil from a soil water mixture, we need to boil it, so it will separate both the soil and water will evaporate.
It takes more heat to boil water than to simply heat water. Unless the water is already at its boiling point.
Water is more viscous than methylated spirits, and vegetable oils are more viscous than water.
because the oil makes the water have more heat which makes the water boil fast.
No, compared to milk, water evaporates much more quickly.
Vegetable oil
It takes less time to boil little amounts of water because there is less water to boil. The more water in the pot, the longer it takes to heat up.
Slower, the more water, the more time required to reach boiling temp.
The actual process of heating would be exactly the same. Microwave energy would begin to excite molecules of water, making them move more quickly and heating them up. Eventually the ice would melt, then boil. The water would heat up then boil.
Less heat will escape with the lid on. As the pressure inside the pan increases, the liquid boils faster - so both aspects combined makes the water to boil faster and save energy. Without a lid, the water won't boil as fast or as quickly, and more energy will be used.
No it actually makes it boil more slowly.
