Question
If we are given the freezing and boiling point of water in an arbitrary temperature scale, we can convert any temperature to another scale by using the equation of a straight line.
Select one:
True
False
Two wheels are made of the same metal and have the same radius, but one is a solid disk and the other is spoked with wires. The wheels are taken through the same temperature increase. Which wheel expands more?
Select one:
a. they expand by the same amount
b. not enough information to say
c. spoked wheel
d. Solid wheel
Explanation / Answer
Answer (1) TRUE
{as we know that relation between different temperature scales are all linear here first of all you can convert these both temperatures from given scale to the known scale by drawing a straight line between these two points you can convert any temperature to the known scale}
Answer (2) a. they expand by the same amount
actually they both expand equally
the spoked wheel will expand as though it were solid disk wheel
this is cause in thermal expansion energy of molecules increases
which leads to an increase in distance between any two points of the solid.
