To calculate the heat needed to boil 38.0 g of water, we use the formula ( q = m \times L_v ), where ( m ) is the mass of the water and ( L_v ) is the latent heat of vaporization of water (approximately 2260 J/g). First, convert the mass to kilograms: 38.0 g = 0.038 kg. Then, calculate the heat: ( q = 38.0 , \text{g} \times 2260 , \text{J/g} = 85,880 , \text{J} ) or 85.88 kJ. Thus, approximately 85.9 kJ of heat is needed to boil 38.0 g of water.

How much time does it take to boil saltwater or pure water?
That is entirely dependent on: 1. Your relation to sea level. 2. How much water you have. 3. How much salt is in the salt water. 4. What amount of heat you are using.
How much heat is needed to boil alcohol?
The amount of heat required to boil alcohol (ethanol) depends on the quantity being heated and its initial temperature. On average, it takes about 207.3 kJ of heat to vaporize 1 mole of ethanol.
How much heat is needed to convert 150 g of ice to water?
41,800
How much heat is needed to freeze 100 g of water?
The heat needed to freeze 100 g of water is 334 J/g. So, for 100 g, the total heat needed would be 334 J/g * 100 g = 33,400 J.
What happen if you continue boil the water above 100 c?
If you continue to boil water above 100°C, the water will not get any hotter because it will all turn into steam. The temperature will remain constant as long as there is water left to boil, but the additional heat will cause more water to turn into steam.
How much heat on to boil Fahrenheit?
For water, 212 F
How much time does it take to boil saltwater or pure water?
That is entirely dependent on: 1. Your relation to sea level. 2. How much water you have. 3. How much salt is in the salt water. 4. What amount of heat you are using.
Can water boil in a solar oven?
Since water is transparent it does not absorb sunlight well, however, you could heat the container that the water is in (especially if it is an opaque container, not a glass container) and then the heated container would heat the water. A solar oven can easily produce enough heat to boil water. If you are not careful it might produce too much heat, and melt the pot.
How much heat is needed to boil alcohol?
The amount of heat required to boil alcohol (ethanol) depends on the quantity being heated and its initial temperature. On average, it takes about 207.3 kJ of heat to vaporize 1 mole of ethanol.
Is the amount of heat required to boil 1kg of water equal to the amount of heat required to melt 1kg of ice?
No, the amount of heat required to boil 1kg of water is much higher than the amount of heat required to melt 1kg of ice. Boiling water requires additional heat to overcome the latent heat of vaporization, while melting ice only requires heat to overcome the latent heat of fusion.
Why does water take so long to warm up?
The specific heat of water determines how much energy is needed to heat water.
Why does it a take a full kettle of water to boil longer than a half full kettle?
The more water in the kettle, the longer it will take to reach boiling point. This is why it is wasteful in energy to boil a full kettle if you only want to brew a small cup of tea.
How much heat requires one litre of water evaporates?
The needed heat is 2 258 kJ.
Why do you boil your water?
to heat it up to cook food, so the heating process isn't nearly as long... you see, without boiling the water before cooking the food, it would take much longer for the food to heat up and cook thoroughly if you boil water prior to cooking it the food, the water is much easier to absorb by the food and you can get the job done quicker, faster, and easier(:
How much heat is needed to convert 150 g of ice to water?
41,800
How long does a kettal take to boil?
depends on the amount of water and how much heat applied. why do people ask STUPID questions on this site?
How much coolant aka water is needed for a nuclear power station?
It depends on how much it needs to be cooled down, or transferred. The more heat there is the more coolant (water) is needed.
