Answer:
The metal will melt but their will be no change in temperature.
Explanation:
The metal is at its melting temperature which means it is still in solid phase but have to cross the enthalpy of its condensation at this same temperature to convert into liquid phase.
<u>On supplying heat, the metal's temperature will not change as the heat will be required as enthalpy of condensation to melt the solid to liquid at the melting temperature.</u>
To develop this problem we will apply the concept related to heat transfer defined as the product between the transfer coefficient and the temperature difference between two spaces, that is,
Here,
h = Heat transfer coefficient
= Temperature at each point
- Interior air and inner wall:
- Outer wall to exterior air:
- Inner wall to interior air:
We can see that the magnitude of the heat fluxes in the three states are the same (The negative sign only indicates the change of direction) so the wall is in steady state conditions
Explanation:
An electric motor is a device that uses an electromagnet to change electrical energy to kinetic energy. When current flows through the motor, the electromagnet rotates, causing a shaft to rotate as well. The rotating shaft moves other parts of the device
