Would you like to make it the primary and merge this question into it?

# If water boils at 100degrees and alcohol boils at 70degreesIf you have 500ml of each at a temperature of 20degrees which liquid would require most heat energy to make it boil?

The water will be require more water because it needs 80degrees more heat than the alchohol which only needs 50degrees more heat.

# How much energy to boil water?

The energy required to boil water will depend upon the starting  temperature of the water, your location above or below sea level,  and the mass of water being boiled. This

# How many joules of energy are necessary to boil the water that has 46g and has the temperature of 100 degreees C?

According to Einsteins theory, the fact that he had only one teste clearly adentifies that the degrees that you have provided are deniable therefore the answer should would an

# How much energy is used to boil a kettle once?

  it costs about 3p to boil a 1/3 full electric kettle at the moment (5.11.08)

# How much does it cost to use geothermal energy?

# How much energy needed to boil 1kg of water from 20 C to 30 C?

Specific heat capacity water - 4.187 kJ/kgK 4.187 kJ/kgK * 10'K * 1Kg = 41.87 Kj

# How much energy is required to heat 955 g of water from 20 degrees C to 100 degrees C?

4.1858 joules of energy will raise the temperature of 1 g of water by 1oC. Thus, 4.1858 * 955 * 80 = 319795.12 joules of energy is required to raise the temperature of 955 g

# How much heat energy is needed to heat a 5.0 gram sample of water from 20 to 30 The specific heat of water is 4.18 J?

Q (heat) = mass*Cp*Temp. Change (where Cp is specific heat) Q = 5.0 grams * 4.18 J/goC * (30-20oC) =5*4.18*10 = 209 J

38% of energy

# How much solar energy is needed to boil water?

Depends how much water and the temperature of the water. To heat 1 mL of water by 1 degree C 1 cal of energy (4.184 Joules) is required. Assuming that the water is at 25 deg
