When ice cube floating in a tumbler of water melts completely why there is no overflow of water?
Its actually quite simple. The answer would be Anomalous expansion of Water, which means that the volume the Ice cubes are consuming in a glass filled upto the brim is more than water alone. When Ice melts and comes back into water form, it uses lesser volume (space) in the glass. Hence it does not allow the glass to overflow as the person pouring into the glass had poured in keeping into view the level of the ice (which uses more volume).
Explain the anomalous expansion of water?
Anomalous expansion of water takes place because when water is heated to 277K hydrogen bonds are formed. Though ice is supposed to expand when it is converted into water, this gradual formation of hydrogen bonds causes it to contract, i.e. the contraction caused due to the formation of hydrogen bonds is greater than the actual expansion of ice. At 277K water has the maximum density because all the hydrogen bonds are formed by 277K beyond which water obeys the kinetic theory of molecules, an increase in volume when heated and the reverse when cooled. The same thing happens in the reverse when water is cooled beyond 277K.
What are Advantages of anomalous expansion of water?
Normally, liquids contract on cooling & become more dense. However, water contracts when cooled to a temperature of 4oC and thereafter expands as it is cooled further from 4oC to 0oC. Water attains its maximum density at 4oC. This phenomenon is useful for the preservation of marine life in very cold temperatures. Initially, the surface water in water bodies starts cooling. Upon reaching the temperature of 4oC, the surface water descends to the bottom as it denser. Upon further cooling between 4-0 degrees C, a temperature gradient is set up in depths of the water body whereby, the bottom-most layer is at 4 deg C & the temperature gradually drops as one goes upwards. At 0 deg C, ice is formed. Ice being lighter than water, floats to the upper surface.and also because ice has space or kind of holes between it's molecules it is able to float in water. Further, water and ice are bad conductors of heat. All this help in the maintenance of temperature of the water at the bottom at 4 deg C. It is in this layer that marine life is able to sustain itself.
What is thermal expansion feed water regulator operated by?
They work when steam and water occupy a tube that is on a slight incline. As water level drops the steam space inside the tube expands. The expanding tube is connected to a linkage which will open the water valve as more steam occupies the tube than water.
Why liquids have two coefficient of expansion?
Because liquids have two types of expansions i.e Apparent Expansion and Real Expansion
Because of this anomalous expansion of water that water pipes sometimes burst during winter?
Anomalous expansion of water and bursting of water pipes during winter is because ice takes more space than water
Why does ice float above and under water?
Ice floats above water, as it has lesser density than that of water. Due to anomalous expansion of water, the ice (solid) has more density than water(liquid). Hence, it floats above water.

Why expansion of water is more than expansion of solids?
The inter atomic force is comparatively less in case of liquid
What happens when volume changes?
Yes under constant pressure, with a given mass, volume changes during the change of state. When steam condenses, its volume is reduced. But, when water changes into ice, its volume becomes more. This is known to be anomalous expansion of water. Where as in other cases, when the liquid form gets changed into solid form, the volume is reduced.
What are the advantages of this wet summer?
because plants get more water
What advantages does a capillary tube have over a thermostatic expansion valve?
Thermostatic expansion valve allows more refrigerant into the evaporator coil during a hot pulldown it allows the evaporator to reach peak performance faster
Advantages of a dam?
Blockage of water creates more farms. Blockage of water creates electricity.
What are the advantages of the GE water heater?
The advantages of the GE water heater are that it is more energy efficient and is more generally environmentally friendly as it lowers the amount of Carbon Dioxide emissions. It will also lower electric heating and water costs for your home.
What is a good sentence using anomalous?
The perfect score she got on the final exam was so anomalous from the dismal scores she'd gotten throughout the semester that the teacher suspected she had cheated.Scientists predict that red-haired people will become progressively more anomalous with each generation, until the gene finally disappears completely.
What are the advantages of Expansionism of China?
Well, the military will benefit as they will hold more power in the Chinese government. The CPC can also use expansion as a diversion from their country's problems and avoid social unrest. Benefits of Expansion would be that China gains more resources that will fuel its growth further.
Advantages of alluvial soil?
There are so many advantages of alluvial soil. Some of the advantages include being fertile, higher water retention capacity as so much more.
