Acopper cylinder is initially at 21.1 ∘c . at what temperature will its volume be 0.163 % larger than it is at 21.1 ∘c?

To solve this problem we will apply the concepts related to the final volume of a body after undergoing a thermal expansion. To determine the temperature, we will use the given relationship as well as the theoretical value of the volumetric coefficient of thermal expansion of copper. This is, for example to the initial volume defined as , the relation with the final volume as

Initial temperature =

Let T be the temperature after expanding by the formula of volume expansion

we have,

Where is the volume coefficient of copper

Therefore the temperature is 53.06°C

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

the answer is to check all of them! they all apply well at least i think so!
