Yes, it is possible to boil water without burning a hole in the cup by using a heat-resistant material such as a ceramic, stainless steel, or glass cup that can withstand high temperatures. It's important to ensure that the cup is suitable for heating and is placed on a proper heat source with the right amount of water inside to prevent overheating.
No, it is not possible to boil water at room temperature (20 degrees Celsius) without applying heat. Boiling water requires reaching its boiling point, which is 100 degrees Celsius at standard atmospheric pressure.
No, it is not possible to boil water in negative temperatures because boiling occurs at 100 degrees Celsius or 212 degrees Fahrenheit, which is above freezing temperatures.
When you place a paper cup filled with water over a direct flame, the water inside heats up and absorbs most of the heat from the flame. The paper cup acts as an insulator, preventing the paper from reaching its ignition temperature due to the presence of water. This allows the water to boil without the paper cup burning.
No, passing steam at atmospheric pressure will not cause water to boil. Boiling occurs when the liquid reaches its boiling point temperature and vapor pressure overcomes the atmospheric pressure. Generally, steam at atmospheric pressure will only cause the water to heat up and potentially evaporate faster.
Electricity can be generated from burning oil by using the heat produced to boil water and create steam. The steam then drives a turbine connected to a generator, which produces electricity. This process is known as thermal power generation.
