How many kilo joules of energy are needed to boil 90 grams of water at its boiling point?
To calculate the energy needed to boil 90 grams of water, we use the formula ( q = m \cdot L ), where ( q ) is the heat energy, ( m ) is the mass of the water, and ( L ) is the latent heat of vaporization for water, which is approximately 2260 kJ/kg. For 90 grams (0.09 kg), the calculation is ( q = 0.09 , \text{kg} \cdot 2260 , \text{kJ/kg} ), resulting in about 203.4 kJ of energy needed to boil the water.

How many joules of heat are needed to completely vaporize 24.40 grams of water at its boiling point?
The heat of vaporization of water is 40.79 kJ/mol. First, determine the number of moles in 24.40 grams of water. Then, convert moles to joules using the molar heat of vaporization. This will give you the amount of heat needed to vaporize 24.40 grams of water.

How many joules are absorbed by the water with a mass of 8 kg in order to raise the temperature from 20 degrees to 70 degrees?
q(joules) = mass * specific heat * change in temperature ( 8 kg = 8000 grams ) q = (8000 grams H2O)(4.180 J/gC)(70o C - 20o C) = 1.7 X 106 joules ============
How many joules of energy are necessary to heat a sample of water with a mass of 46.0 grams from 0.0 celsius to 100.0?
419.1 Joules are required to heat one gram of liquid water from 0.01 degC to 100 deg C. So the answer is 419.1*46 = 19278.6
