You need to add all of the following:* The heat required to heat ice from -5 to 0 degrees. Multiply the mass times the temperature difference times the specific heat of ice.
* The heat required to melt ice. Multiply the mass by the heat of fusion.
* The heat required to raiste the temperature of water from 0 to 20 degrees. Multiply the mass times the temperature difference times the specific heat of water.
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.
The amount of heat that must be removed from steam to change it to a liquid is the latent heat of vaporization of water, which is approximately 2260 kJ/kg at atmospheric pressure. This is the amount of energy required for water to change from a gas to a liquid state at a constant temperature.
To change 1 kg of ice at 0°C to water at 0°C, you would need 334 kJ of heat energy. This includes the heat required to raise the temperature of the ice to 0°C (latent heat of fusion) and then to melt it into water at 0°C.
The amount of heat energy transferred to hot water depends on various factors such as the initial and final temperatures of the water, the mass of the water, and the specific heat capacity of water. The formula to calculate heat energy transferred is: Q = mcΔT, where Q is the heat energy, m is the mass of the water, c is the specific heat capacity of water, and ΔT is the change in temperature.
Heat of vaporization or enthalpy of vaporization. It is the additional energy, per unit mass, required after vaporization temperature (boiling point) is reached, to accomplish the change in state, from liquid to gas.
To change the temperature of water from 27ºC to 32ºC will depend on the mass of water that is present. Obviously, the more water, the more heat it will take. This can be calculated as follows:q = heat = mC∆T where m is the mass of water; C is sp. heat = 4.184 J/g/deg and ∆T is 5ºC (change in temp).
The necessary heat is 9,22 joules.
The idea here is to: * Look up the specific heat of water. * Multiply the mass, times the temperature difference, times the specific heat of water. You may need to do some unit conversions first; specifically, if the specific heat is given per kilogram, you can convert the grams to kilograms.
Heat required to have such a change of state is called latent heat. If L J/kg is the latent heat per kg of water then for M kg of water we need M* L joule of heat energy
water has a high heat of vapourization.it absorbs much heat as it changes from liquid to gas.it has the capacity of absorbing heat with minimum of change in its own temperature

The equation is q = mC∆T where q is the heat; m is the mass of water; C is the specific heat of water (1 cal/g/deg); and ∆T is the change in temperature.

If there is too much water, people are flooded out of their homes. If there is not enough water, you have drought, and that leads to heat stroke, thirst, and hunger.
