Short Answer

What is the temperature of ice right after it is formed by freezing water?

The temperature of ice at which water is completely transferred to ice is slightly less than 0oC

Step by Step Solution

TABLE OF CONTENTS :
TABLE OF CONTENTS

Step 1: Describe the scenario

The temperature at which a liquid transform into a solid is called its freezing point. The freezing point of water is 0oC . At this temperature, water begins to freeze. In this scenario, the temperature of the ice at which it is completely transformed into its solid form by the freezing water has to be calculated. For that, we need to observe the graph of temperature versus energy.

Step 2: Observe the graph of temperature versus energy

Consider the graph of temperature verses energy. It gives the idea of how phase changes with the temperature.

From this graph, we can understand that at 0oC , there will be water and ice. When the temperature falls below 0oC , the water becomes completely transformed into ice.

So, the temperature of ice at which ice is formed from freezing water is slightly less than 0°C.

What are the main methods of heat transfer from the hot core of Earth to its surface? From Earth’s surface to outer space?

When our bodies get too warm, they respond by sweating and increasing blood circulation to the surface to transfer thermal energy away from the core. What effect will this have on a person in a \({\rm{40}}{\rm{.}}{{\rm{0}}^{\rm{o}}}{\rm{C}}\) hot tub?

Figure shows a cut-away drawing of a thermos bottle (also known as a Dewar flask), which is a device designed specifically to slow down all forms of heat transfer. Explain the functions of the various parts, such as the vacuum, the silvering of the walls, the thin-walled long glass neck, the rubber support, the air layer, and the stopper.

What effect does condensation on a glass of ice water have on the rate at which the ice melts? Will the condensation speed up the melting process or slow it down?

Consider a new model of commercial airplane having its brakes tested as a part of the initial flight permission procedure. The airplane is brought to take off speed and then stopped with the brakes alone. Construct a problem in which you calculate the temperature increase of the brakes during this process. You may assume most of the kinetic energy of the airplane is converted to thermal energy in the brakes and surrounding materials, and that little escapes. Note that the brakes are expected to become so hot in this procedure that they ignite and, in order to pass the test, the airplane must be able to withstand the fire for some time without a general conflagration.

A large body of lava from a volcano has stopped flowing and is slowly cooling. The interior of the lava is at 1200ºC , its surface is at 450ºC , and the surroundings are at 27.0ºC . (a) Calculate the rate at which energy is transferred by radiation from \({\bf{1}}{\bf{.00 }}{{\bf{m}}^{\bf{2}}}\) of surface lava into the surroundings, assuming the emissivity is 1.00. (b) Suppose heat conduction to the surface occurs at the same rate. What is the thickness of the lava between the 450ºC surface and the 1200ºC interior, assuming that the lava’s conductivity is the same as that of brick?

If you place \({{\rm{0}}^{\rm{o}}}{\rm{C}}\) ice into \({{\rm{0}}^{\rm{o}}}{\rm{C}}\) water in an insulated container, what will happen? Will some ice melt, will more water freeze, or will neither take place?
