Yes, you should. However, that said, when the water first starts to boil, you turn down the heat to low, and keep it there until the time is up: 20 minutes for white rice, 40 minutes for brown. You should heat it in a covered pan. The lid should remain on the pan for the entire process. Add salt to the water (but not too much) before boiling.
it should. maybe the lab is warm or cold
To boil water, fill a pot with water and place it on a stove over high heat. Wait until bubbles start to form and the water is rapidly boiling. You can tell the water is boiling when steam starts to rise from the surface.
Cover the chicken with cold water, bring it to a boil and then lower the heat to a bare simmer. When there is no more pink in the meat near the bone, it's done. For a whole chicken that could take up to an hour.
So we won't get sick.
Hot water takes longer to boil than cold water because hot water is already closer to its boiling point, so it requires more energy to reach the boiling point compared to cold water.

Rinse under cold water then place it in boiling water with some salt. Let the tripe boil for two to three hours. Place the tripe in a pot of cold water and let it soak in the water overnight. Scrape the insides using a knife to remove any remaining grit.
well, it does not really matter, although cold water in a kettle takes longer to boil
Yes, hot water boils faster than cold water because the molecules in hot water have more energy and are already closer to the boiling point. This means it takes less time and energy to raise the temperature of hot water to the boiling point compared to cold water.
No, hot water boils faster than cold water because it is already closer to the boiling point.
If you are looking at decreasing cooking time you would use cold water. Thermal exchange causes the water temperature to have a drastic increase. If you are just cooking the egg then it doesn't really matter.
Boil it and then leave it in cold water to cool down.
