Explanation of Solution
Write the expression for the expression for the heat liberated when temperature of a substance reduces.
Here,
The specific heat of steam is
Substitute
Write the expression for the heat liberated when steam becomes water at the boiling point of water.
Here,
The heat of vaporization for water is
Substitute
The specific heat of water is
Substitute
Thus, the total heat liberated when
When the steam liberate
Write the expression for the heat corresponding to the phase change of water at
Here,
The heat of fusion of water is
Substitute
So, liberation the
Conclusion:
Since, the liberated heat energy of
The liberated heat energy of
Since there is energy lost from the system even after it become completely water, the final state is not only consist of water but also ice. Thus, option (c) is incorrect.

- The latent heat of vaporization for water at room temperature is 2 430 J/g. Consider one particular molecule at the surface of a glass of liquid water, moving upward with sufficiently high speed that it will be the next molecule to join the vapor. (a) Find its translational kinetic energy. (b) Find its speed. Now consider a thin gas made only of molecules like that one. (c) What is its temperature? (d) Why are you not burned by water evaporating from a vessel at room temperature?arrow_forwardA large room in a house holds 975 kg of dry air at 30.0C. A woman opens a window briefly and a cool breeze brings in an additional 50.0 kg of dry air at 18.0C. At what temperature will the two air masses come into thermal equilibrium, assuming they form a closed system? (The specific heat of dry air is 1 006 J/kg C, although that value will cancel out of the calorimetry equation.)arrow_forwardem>. The volume of an ideal gas enclosed in a thin, elastic membrane in a room at sea level where the air temperature is 18°C is 8 10-3 m3 .If the temperature of the room is increased by 10°C, what is the new volume of the gas?arrow_forward
- An ice-cube tray is filled with 75.0 g of water. After the filled tray reaches an equilibrium temperature 20.0C, it is placed in a freezer set at 8.00C to make ice cubes. (a) Describe the processes that occur as energy is being removed from the water to make ice. (b) Calculate the energy that must be removed from the water to make ice cubes at 8.00C.arrow_forwardIf you place 0C ice into 0C water in an insulated container, what will happen? Will some ice melt, will more water freeze, or will neither take place?arrow_forwardA cylinder of volume 50.0 cm3 made of Pyrex glass is full to the brim with acetone. If the cylinder and acetone are warmed by 30.0C, (a) what is the change in volume of the glass? (b) Of the acetone? (c) Will any acetone spill out of the cylinder? (See Section 10.3.)arrow_forward
- In some countries, liquid nitrogen is used on dairy trucks instead of mechanical refrigerators. A 3.00-hour delivery trip requires 200 L of liquid nitrogen, which has a density at 808kg/m3. (a) Calculate the heat transfer necessary to evaporate this amount of liquid nitrogen and raise its temperature to 300C. (Use cp and assume it is constant over the temperature range.) This value is the amount of cooling the liquid nitrogen supplies. (b) What is this heat transfer rate in kilowatthours? (c) Compare the amount of cooling obtained from melting an identical mass at 0C ice with that from evaporating the liquid nitrogen.arrow_forwardYou are working in your kitchen preparing lunch for your family. You have decided to make egg salad sandwiches and are boiling six eggs, each of mass 55.5 g, in 0.750 L of water at 100C. You wish to take all the eggs out of the boiling water and immediately place them in 23.0C water to cool them down to a comfortable temperature to hold them and peel them. You decide that you wish the mixture of the water and the eggs to reach an equilibrium temperature of 40.0C. Explaining this to a family member, she challenges you to determine exactly how much water at 23.0C you need to achieve your desired equilibrium temperature. Take the average specific heat of an egg over the expected temperature range to be 3.27 103 J/kg C.arrow_forwardAn aluminum rod and an iron rod are joined end to end in good thermal contact. The two rods have equal lengths and radii. The free end of the aluminum rod is maintained at a temperature of 100.C, and the free end of the iron rod is maintained at 0C. (a) Determine the temperature of the interface between the two rods. (b) If each rod is 15 cm long and each has a cross-sectional area of 5.0 cm2, what quantity of energy is conducted across the combination in 30. min?arrow_forward
- - (a) Compute the amount of heat needed to raise the temperature of 1 kg of water from its freezing point to its normal boiling point. (b) How does your answer to (a) compare to the amount of heat needed to convert 1 kg of water at 100° C to steam at 100°C?arrow_forwardIf you pour 0.0100 kg of 20.0C water onto a 1.20kg block of ice (which is initially at 15.0C ), what is the final temperature? You may assume that the water cools so rapidly that effects of the surroundings are negligible.arrow_forwardAn ice-cube tray is filled with 75.0 g of water. After the filled tray reaches an equilibrium temperature 20.0C, it is placed in a freezer set at 8.00C to make ice cubes.
