The two spheres will expand equally since they are made of the same metal.
<h3>
What is volume expansivity?</h3>
Volume expansivity is the fractional increase in the volume of an object at a given temperature.

where;
- γ is cubic expansivity
- ΔT is change in temperature
The cubic expansivity of the two spheres is same since they are of same metal.
Thus, the two spheres will expand equally since they are made of the same metal.

The answer to your question is "Yes". Great numbers of people ... chemists,
physicists, and common folks alike ... know what Uranium is.
=================================
Uranium is one of the 92 elements that are found to occur in nature.
In the Periodic Table of the Elements, it is Element #92 ... Its atoms
contain 92 protons in their nucleii.
electromagnetic spectrum is consisting of many frequency range which is from gamma rays to radio waves
they are of various wavelength and different energy levels
minimum wavelength will occurs at Gamma rays
and maximum wavelength at Radio waves
the list of increasing order of wavelength is as following
Gamma rays < X rays < Ultraviolet < Visible Light < Infrared Waves < Radio Waves
so least to maximum order is
1. Gamma rays
2. X rays
3 Ultraviolet
4 Visible light
5 Infrared waves
6 Radio waves
