What is apparent and real expansion of liquids expansion?
Apparent expansion of a liquid is the increase in volume which appears to have taken place if no notice is taken. Real expansion is the actual increase in volume of a liquid per unit volume per degree rise in temperature
What is expansion of liquid?
expansion of liquids
Why liquids have two coefficient of expansion?
Because liquids have two types of expansions i.e Apparent Expansion and Real Expansion
What is the apparent mass in water?
Apparent Weight =weight Of Water- Upward Thrust =(mg- Density Of Water Displaced*volume Of Liquid*gravity)
What makes a liquid in glass thermometer sensitive to a small changes in temperature?
A liquid in glass thermometer is sensitive to small changes in temperature due to the thermal expansion of the liquid contained inside the glass tube. As the temperature increases, the liquid expands, causing it to rise up the calibrated scale of the thermometer. Conversely, as the temperature decreases, the liquid contracts, causing it to subside on the scale. This expansion and contraction of the liquid is highly responsive to even slight temperature variations, making it sensitive to small changes in temperature.
What is apparent and real expansion of liquids expansion?
Apparent expansion of a liquid is the increase in volume which appears to have taken place if no notice is taken. Real expansion is the actual increase in volume of a liquid per unit volume per degree rise in temperature
What is expansion of liquid?
expansion of liquids
What is the expansion rate of nitrogen liquid to gas?
The expansion rate of liquid nitrogen is 697 to 1.
How do thermometers with in liquid in glass measure temperature?
Such thermometers are based on the fact that the liquid expands when the temperature increases. That's what the thermometers measure.
Why liquids have two coefficient of expansion?
Because liquids have two types of expansions i.e Apparent Expansion and Real Expansion
Dry expansion evaporator?
In dray expansion evaporator, the liquid refrigerant is generally fed by an expansion valve. the expansion valve controls the rate of flow of refrigerant to the evaporator. In the evaporator the liquid refrigerant is vaporized and superheated by the time it reaches to the end of evaporator. At inlet of the evaporator, the refrigerant is predominantly in the liquid form with a small amount of vapor formed as a result of flashing at the expansion valve. the liquid refrigerant passes through the evaporator, more and more refrigerant is vaporized by the load. according to the load, the liquid will come into evaporator and vaporize and reaches to superheat at the end of the evaporator. The inside of the evaporator is far from dry but wetted with liquid so named as dry expansion evaporator.
What does heat do to liquid?
It makes the liquid particles move faster. This results in expansion and temperature rise.
What is the apparent mass in water?
Apparent Weight =weight Of Water- Upward Thrust =(mg- Density Of Water Displaced*volume Of Liquid*gravity)
Why expansion of water is more than expansion of solids?
The inter atomic force is comparatively less in case of liquid
Where do humans make use of expansion?
thermometers (liquid mercury)
Does all liquid has the same rate of expansion and contraction?
No, they vary
What happens when liquid in a thermometer undergoes thermal expansion?
The liquid rises, indicating a temperature.
