It will become shorter as it cools. Heating causes most metals to expand in volume.
The mercury is at ambient temperature.
no, it would be a physical change (with reservations) [depending on HOW you change the size]
.... by measurement with an device designed for one particular property: balance for mass, thermometer for temperature, ruler for length, spectrophotometer for color, photometer for light, etc.
Ans. Thermometric Well Fig. 3.6 shows an arrangement which is used to measure the temperature of gas flowing through a pipeline. A small tube called thermometric well is welded radially into the pipeline.The well is partially filled with some liquid and the thermometer is immersed into this liquid. When the temperature of the gas flowing through the pipeline is higher than the ambient temperature, the heat flows from the hot gases towards the tube walls along the well.This may cause temperature at the bottom of well to become colder than the gas flowing around. Obviously the temperature indicated by the thermometer will not be the true temperature of the gas. The error in the temperature measurement is estimated with the help of the theory of fins.The protective tube (well) can be considered as a hollow fin (internal diameter d,thickness ö and length 1), and the temperature distribution obtained by using the relation applicable to a fin with tip insulated:where is the temperature of the pipe wall, ta is the temperature of hot gas or air flowing through the pipeline, and is the temperature at any distance x measured from pipe wall along the thermometric well.If x = 1 then,where t1 is the temperature recorded by the thermometer at the bottom of well and represents error in temperature measurement.The perimeter of the protective well P = and its cross-sectional area Therefore,then,
It is impossible to tell how long from the start of the experiment it was before all of the substance turned into a liquid without more information about the experiment. Perform the experiment again and use a timer to determine the length of time required to turn the substance into a liquid through heating.
If you dont know this your not an engineer!
The difference in expansion of two objects having different length and heated in same temperature difference is called differential expansion.
Yes. ensure that meat is defrosted fully and it has been heated evenly to the proper temperature for the correct length of time.
If the whole volume has stabilized from convection movement, then there shouldn't be a difference in temperature.
strlen
To get the length of the string we use length property. The length property returns the length of a string (number of characters we use).If the string is empty, length of the string will be 0. Syntax: string.length Hope this helps.
All metals expand when heated and contract when cooled. It is important, therefore, that the standard metre is kept at some constant temperature. That constant temperature could be any temperature but the triple point of water is a convenient benchmark.
The Meter (length) and Kelvin (temperature)
no , all solids do not expand by the same amount when heated through same temperature. it depends upon the coefficient of its linear expansion. We define avergae co-efficient of linear expansion in the temperature range deltaT as α=(1/L)(ΔL/ΔT) where L is initial length of the solid at the temperature T.. It varies from material to material , higher the value of alpha , it expands more..
Cold forming is a high speed forging process in which coiled wire is heated to room temperature and is precisely sheared to length, then moved through a succession of tools to finalize the product.
