How is cubical expansion calculated?
“VOLUMETRIC EXPANSION ” or “CUBICAL EXPANSION”. Consider a metallic body of volume = V1 . Let it’s temperature is raised by T. then experimentally “Increase in volume ( V) is directly proportional to its initial volume (V1) and rise in temperature ( T).
What is an example of anomalous Behaviour of water?
Answer. water has a unique property of anomalous expansion. When water is cooled from room temperature it first contracts in volume and becomes increasingly dense as do other liquids, but at 4° C water reaches its maximum density. On further cooling it starts expanding and become less dense.
What is the reason behind the anomalous Behaviour of water?
Heat Transfer | Short/Long Answer Questions Water does not expand between 0°C to 4°C instead it contracts. It expands above 4°C. This means water has maximum density at 4°C. This is called anomalous behaviour of water.
What do you mean by animal is Behaviour of water?
When water is heated from 0°C to 4°C it CONTRACT and density INCREASE, heating water above 4°C starts expanding and density of water decrease. This means water has a maximum density at 4°C. This is called anomalous behaviour of water.
What is meant by anomalous?
1 : inconsistent with or deviating from what is usual, normal, or expected : irregular, unusual Researchers could not explain the anomalous test results. 2a : of uncertain nature or classification an anomalous figure in the world of politics. b : marked by incongruity or contradiction : paradoxical.
How do you study anomalous behavior?
Isolate the device and put two thermometers into the two holes of the apparatus respectively. The inner cylinder is filled with pre-cooled water while the outer cylinder is filled with the cooling mixture. The temperatures are observed on the thermometers and anomalous behaviour of water is noted.
What is hope apparatus?
Hope’s apparatus consists of a vertical vessel full of water surrounded round the middle by a trough of cooling ice. Two thermometers, one above and one below the trough, measure the temperature of the water. It is designed to demonstrate that water reaches its maximum density at 4 °C (39 °F).
