How much heat is needed to convert 150 g of ice to water?

If 30.86g of H2O is frozen (from liquid to solid) how much heat energy is required?
No heat (energy) is required to freeze water (from liquid to solid). Freezing RELEASES energy (heat), as it is an exothermic event. If you want to know how much energy is release, you need to know the heat of fusion for water, and then multiply that by the mass of water being frozen.
How much energy is needed to melt 0.25 moles of water?
The necessary heat is 9,22 joules.
A quantity of steam at 110 C is condensed and the resulting water is frozen into ice at 0 C. How much heat was removed?
The amount of heat removed during the process of steam condensing and then freezing into ice is calculated by adding the heat required to condense the steam and the heat required to freeze the resulting water. This is determined using the specific heat capacity and latent heat of vaporization/condensation for water.
How much heat energy is needed to vaporize g of water at its boiling point of K?
1oo calories for 1 g
Why does water take so long to warm up?
The specific heat of water determines how much energy is needed to heat water.
How much heat requires one litre of water evaporates?
The needed heat is 2 258 kJ.

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.

How much energy to burn a calorie?
A calorie is the amount of energy needed to heat 1 gram of water by 1 degree Celsius. So you can't burn a calorie.
How much energy is needed to melt 0.25 moles of water?
The necessary heat is 9,22 joules.
How much heat is needed to raise 8 kg of water from 4 degrees Celsius to 83 degrees Celsius?
The heat needed can be calculated using the formula: Q = mc∆T, where Q is the heat, m is the mass of water, c is the specific heat capacity of water (4186 J/kg°C), and ∆T is the change in temperature. Plug in the values to find the heat needed.
How much heat is in fresh water?
It would depend on the temperature of the water, or average kinetic energy. (KE) However, what you may be looking for is how much heat is needed to raise the KE, or temperature, of water. 4.184 kilojoules per gram is the heat required to raise the temperature of water 1 degree Celsius.
How much heat is necessary to change 565 g of ice at -13 and degC to water at 20 and degC?
To calculate the heat needed to change ice to water, we use the specific heat capacities and latent heat of fusion. First, calculate the heat needed to raise the temperature of 565 g of ice from -13°C to 0°C using specific heat capacity of ice. Then, calculate the heat needed to melt the ice at 0°C to water at 0°C using the latent heat of fusion for ice. Finally, calculate the heat needed to raise the temperature of water from 0°C to 20°C using the specific heat capacity of water. Add these three values together to find the total heat required.
How much heat is needed to raise kg of water from 4 degrees Celsius to 83 degrees Celsius?
2,641,760J...
How much heat is needed to heat 100g of water from 10 to 95 degrees?
A calorie of energy (NOT to be confused with a Calorie, they are different so watch the caps) is the amount necessary to heat 1 gram of water 1oC, so 30 calories are needed to heat 30 g of water 1 degree. To heat it 70oC would take 2100 calories (or 2.1 Calories) of energy.
