Interpretation: The amount of evolved heat in kilojoules needed to warm given amount of ice is to be calculated.
Concept Introduction: The amount of heat required to melt 1 mole of a solid is known as heat of fusion. It is denoted by the symbol
The amount of heat required to vaporize 1 mole of liquid is termed as heat of vaporization.
It is denoted by the symbol
For water,
Calculate the heat released by water as:
Here, m is the mass of water, C is the heat capacity of water in that state and
For liquid water, heat capacity is
For steam, heat capacity is
For ice, heat capacity is

- Explain why 15 g of steam at 100C melts more ice than 15 g of liquid water at 100C.arrow_forwardSilicon carbide, SiC, is a very hard, high-melting solid. What kind of crystal forces account for these properties?arrow_forwardHeat is added to ice at 0 C. Explain why the temperature of the ice does not change. What does change?arrow_forward
- Arrange the following substances in order of increasing strength of crystal forces: CO2, KCl, H2O, N2, CaO.arrow_forwardWhite phosphorus, P4, is normally a white, waxy solid melting at 44C to a colorless liquid. The liquid has a vapor pressure of 400.0 mmHg at 251.0C and 760.0 mmHg at 280.0C. What is the heat of vaporization of this substance?arrow_forwardTrichloroethane, C2H3Cl3 is used as a degreaser (solvent for waxes and oils). Its density is 1.435 g/mL and its vapor pressure at 20C is 124 mm Hg. (a) How many mL will vaporize in an evacuated 1.50-L flask at 20C? (b) A 3.00-mL sample is poured into an evacuated 1.5-L flask at 20C. Will all the liquid vaporize? If not, what is the pressure in the flask? (c) A similar 3.00-mL sample is poured into an evacuated 20.00-L flask at 20C. What physical state(s) is/are in the flask?arrow_forward
