The heat of vaporization for liquid zinc is 1.76 kJ per gram. How much heat is needed to boil 11.2 g of liquid zinc already at its boiling point?

Multiply delta H (1.76 kJ/g) by mass (11.2g)
That results in 19.7 kJ, convert to J. (1 kJ=1000J)
The answer would be 19,700 J or 19.7 kJ, depending on your units.

The heat needed to boil away one gram of a liquid at its boiling point is?
The heat needed to melt one gram of a solid at its melting point is the heat of fusion.
What is the amount of energy needed to vaporize one gram of a liquid?
Heat of vaporization
What information does the latent heat of vaporization give?
The energy needed to completely vaporize a mole of a liquid
If a susbtance has a high heat of vaporization what does this mean in terms of the quality of heat needed for the evaporation of this liquid?
It's not the quality of the heat, but the quantity of the heat. It means you need to put a large amount of (heat) energy into that substance to convert it from liquid to vapor at the same temperature. (Check out boiling water.)
What is the heat energy needed to change a liquid to gas while the temperature stays the same?
(latent) heat of vaporization
What is the relation of the molar heat of fusion to the molar heat of vaporization?
Molar heat of fusion: the heat (enthalpy, energy) needed to transform a solid in liquid (expressed in kJ/mol). Molar heat of vaporization: the heat (enthalpy, energy) needed to transform a liquid in gas (expressed in kJ/mol).
What Heat of is the energy needed for a substance to change from liquid state to a gaseous state?
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.
The heat needed to boil away one gram of a liquid at its boiling point is?
The heat needed to melt one gram of a solid at its melting point is the heat of fusion.
What is the energy needed for a substance to change from liquid state to a gaseous state?
thermol
What is the energy needed to chage a material from a liquid to a gas?
heat of vaporization
What is the latent heat of vaporization?
It is the additional amount of heat [measured in (the "big") calories ] required to cause boiling/vaporization of a liquid already at the boiling/vaporization temperature. Heat of vaporization is the amount of heat (540 calories/gram) needed to change a specific amount of liquid (1 gram) at it's boiling point into a gas without changing it's temperature. -Qwasas
What is the engery required to go from liquid to gas called?
The energy needed to go from a liquid to a gas is referred to as heat of vaporization.
The amount of energy needed to change a material from a solid to a liquid is the heat of what?
The latent heat of evaporation
What is the amount of energy needed to vaporize one gram of a liquid?
Heat of vaporization
What is water and heat of vaporization?
Heat of Vaporization id the amount of heat needed to transform a liquid into a gas while not raising its temperature.
what does Boils mean?
partly boiled. The food is partly cooked and finished off when needed.
What is the name of the energy needed to change a substance from a liquid to a gas?
The energy needed to change a substance from a liquid to a gas is called the enthalpy (or heat) of vaporization.
