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.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

explanation:

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
