What is the temperature of the mercury when the length of the mercury thread is 8cm?
The length of a mercury thread in a thermometer is not directly related to the temperature of the mercury. The temperature is denoted by the level that the mercury rises to in the calibrated tube. The length of the mercury thread only indicates the volume of mercury present.
What happens to the matter in copper wire when heated?
When copper wire is heated, the atoms within the wire vibrate more vigorously, leading to an increase in kinetic energy. This causes the wire to expand slightly in length and thickness. If heated excessively, the wire can eventually melt and transform into a liquid state.
Why the end of a glass rod becomes round on heating reason?
when glass rod is heated ,it melts. Now a liquid having surface tension ,tends to have least surface area.we know that a spherical surface has least surface area compared to other shapes of same volume.so end of a glass rod becomes round when heated .........geddit :)
What are the physical properties of shortening?
The process of shortening has the effect of decreasing the physical length or distance of the object or path on which it acts. The process is typically implemented in a progressive, measured manner, but can also be applied suddenly and precipitously, and is then referred to as 'cutting', 'chopping', or 'hacking'.
How long from the from the start of the experiment was the substance heated before all of the substance turned into a liquid?
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.
What is the nature of graph between length and temperature of a heated metal?
The graph between the length of a heated metal and its temperature typically exhibits a linear relationship, demonstrating thermal expansion. As the temperature increases, the length of the metal also increases due to the increased kinetic energy of the atoms, causing them to move further apart. This relationship is generally described by the linear expansion formula, which states that the change in length is proportional to the change in temperature. However, this linearity holds true only within a certain temperature range for most materials.
What is expansion differential?
The difference in expansion of two objects having different length and heated in same temperature difference is called differential expansion.
How do properties change when a heavily cold worked metal is heated above crystallization temperature for sufficient length of time?
If you dont know this your not an engineer!
Can chicken be reheated if previously frozen?
Yes. ensure that meat is defrosted fully and it has been heated evenly to the proper temperature for the correct length of time.
What is the difference in temperature of water per centimeter or unit length in a tank of heated water assuming the whole volume has stabilised from convection movement.?
In a tank of heated water with stable convection movement, the temperature difference per unit length would depend on the specific temperature profile established in the tank. This would be influenced by factors such as the heating source, tank material, and flow characteristics. Generally, the temperature difference per unit length would diminish as you move away from the heat source towards the edges of the tank where heat dissipation occurs.
What function returns the length of a string?
strlen
How is increased in length proportional to the rise in temperature?
When a material is heated, its molecules gain energy and vibrate faster, causing them to take up more space and expand. The increase in length of a material is proportional to the rise in temperature because as temperature increases, the average energy of the molecules also increases, leading to greater expansion and lengthening of the material.
What is the constant string length method?
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.
Why is 1 meter length kept in 0 degree Celsius?
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.
If a steel rod of 10 meters in length was heated so that its temperature rose by 10 'c how long would the rod become?
When a steel rod is heated, it expands due to thermal expansion. The change in length can be calculated using the formula: ΔL = α * L0 * ΔT, where ΔL is the change in length, α is the coefficient of linear expansion for steel (approximately 11 x 10^-6 /°C), L0 is the original length (10 meters), and ΔT is the change in temperature (10°C). Applying this, the rod would expand by about 0.0011 meters or 1.1 millimeters, resulting in a new length of approximately 10.0011 meters.
What are the SI base units for length and temperature?
The Meter (length) and Kelvin (temperature)
Do all solids expand by the same amount when heated through same 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..
