WebThe vast majority of energy needed to boil water comes right before it's at the boiling point. It takes way less energy to heat water to 90ºC than to 100ºC, so the relative amounts of energy required to boil ethanol vs. water are actually as large as stated in the video. Web30 jun. 2024 · Given, the amount of water, m= 21.1 g. We know that, the heat of vapourization of water = The latent heat of vaporization (q) is calculated as: q = mH. q = (21.1 g) × (2260J/g) q = 47686 J. Therefore, the 47686 Joules are required to boil 21.1 g of water at a temperature of 100°C. Learn more about latent heat of vaporization, here: …

Amount of Energy Needed for Boiling a Litre of Water
WebWater has a specific heat capacity of 4,200 Joules per kilogram at 4 degrees Celsius (J/kg°C). This means that raising the temperature of 1 kg of water by 1°C requires 4,200 J. Because it doesn’t take much energy to change the temperature of lead, it will warm up and cool down faster. How do you calculate the amount of energy required to ... Web15 jul. 2024 · It takes around 8 to 10 minutes to boil 1 liter of water (4 cups) in a pot on the stove over high heat with the cover on. In an electric kettle, 1 liter of water takes roughly 4 to 5 minutes to boil. In a microwave, boiling 1 liter of water takes roughly 3 to 4 minutes. If you merely want to boil 1 cup of water, you will only need to wait 1-3 ... WebWhat c in the equation is, the specific heat capacity. So in water it takes 1200 joule’s to raise a Kg of water by 1 degree K or in degrees C. If this takes 1 min to boil the power required … how much is kidtopia
