Uh, no.
The vibrations impinging on the diaphragm produce
corresponding eletrical signals. 1 kHz in, 1 kHz out,
simple as that.
If "a hot microphone produce a different range of
sounds than a cold one," you have a seriously broken
microphone: throw it out.
Microphone sensitivity, noise level and even relibility
can change with temperatire, but there's no physical
mechanism, which can cause an operating microphone
listening to one range of frequencies to change them
into some other range.
