Can energy change in physical change

“Physical changes involve small changes in energy and are easily reversible. A chemical change may involve a decomposition or synthesis reaction. During chemical change, the mass and number of atoms is conserved, but the number of molecules is not always the same. Chemical reactions involve larger changes in energy.” (open stacks) hope this helps!

Year  1936,  lehman predicted that the earths 'inner core' is solid. she observed that the seismic signals during her study were bent and did not pass through instead bouncing back. later it was confirmed that the earth's inner core was solid made up of nickel-iron and had a molten outer core.

An adiabatic process is one which occurs without the transfer or matter or heat in a system.
