How are Q and W related during this isothermal expansion?View Available Hint(s)How are and related during this isothermal expansion?Both Wand Qequal zero. Both Wand Qprovide energy input. Both Wand Qprovide energy output. Wprovides energy output, while Qprovides energy input. They are equal in magnitude. Wprovides energy input, while Q provides energy output. They are equal in magnitude.

W provides energy output, while Q provides energy input and They are equal in magnitude

Explanation:

ISOTHERMAL EXPANSION is thermodynamic process, where there is no change in the temperature the system.

"Q" means heat while "W" means work.

From the first law of thermodynamics,

dU = dQ – dW

Where

dW = pdV

FOR ISOTHERMAL process

dU = 0 ( there is no change internal energy and the system is loosing the internal energy due to work "W")

dQ – dW=0

dQ=dW

W=Q (for an ideal gas)

*Therefore both Q and W are equal in magnitude because the system needs more internal energy due to loss of energy during Work.

In conclusion "W" provides energy output, while Q provides energy input.

c)as speed changes, wavelength and frequency change.

everything changes!
