What metal has the hightest thermal expansion?
Generally speaking, it is tungsten.
When a bimetallic strip is heated it bends toward the metal with the thermal expansion?
When a bimetallic strip is heated, the metal with the higher coefficient of thermal expansion expands more than the other metal, causing the strip to bend towards that metal. This bending is due to the unequal expansion and contraction of the two metals when exposed to different temperatures.
Why is an optical lever used to measure the expansion of the metal tube in the thermal expansion experiment?
An optical lever is used because it magnifies small changes in length, making it easier to detect the expansion of the metal tube. The lever amplifies the displacement of the marker on the tube, allowing for more precise measurement of thermal expansion. This method provides accurate and reliable results in determining the expansion coefficient of the metal.
Use thermal expansion in a sentence?
When the metal bridge heated up in the summer sun, it expanded due to thermal expansion, causing the joints to shift slightly.
What is an examlpe of a difficulty caused by thermal expansion?
A common difficulty caused by thermal expansion is the warping or cracking of materials such as metal or concrete when they are exposed to extreme temperature changes. For example, railroad tracks can buckle in hot weather due to thermal expansion if proper allowances are not made.
What is the hindiequivalent for derailment?
The metal undergoes thermal expansion

What is a jar with its lid on tightly an example of?
Thermal expansion and contraction, specifically the different coefficients of thermal expansion (CTE) between glass and metal....AND ITS LIKE A (CLOSED SYSTEM)

What are two examples of thermal expansion in solid?
Two examples of thermal expansion in solids are the expansion of a metal rod when heated, causing it to increase in length, and the expansion of a bridge beam on a hot day, resulting in the beam bending slightly due to the increase in temperature.

What is the process called when heat causes metal to expand?
The process is called thermal expansion. When metal is heated, the increase in temperature causes its particles to vibrate more vigorously, leading to an expansion in size.
Would the gap in a metal ring increase as it is heated?
Yes, as the metal ring is heated, it will expand due to thermal expansion. This expansion will cause the gap in the ring to increase in size.
Deformation of bi-metal when heated up?
When a bi-metal strip is heated, the two metals it is made of expand at different rates due to their different coefficients of thermal expansion. This causes the bi-metal strip to bend or deform, curving towards the side of the metal with the higher coefficient of thermal expansion. This property is utilized in devices such as thermostats to control temperature.
How can expanding metal be measured?
Metal expansion can be measured using a variety of instruments like thermometers, thermocouples, or strain gauges. By subjecting the metal to different temperatures and observing the resultant expansion, the coefficient of thermal expansion can be calculated. Additionally, techniques such as interferometry or laser holography can be used to measure the expansion of metals with high precision.
