Arigid container equipped with a stirring device contains 1.5 kg of motor oil. determine the rate of specific energy increase when heat is transferred to the oil at a rate of 1 w and 1.5 w of power is applied to the stirring device.

To solve this problem we will apply the first law of thermodynamics which details the relationship of energy conservation and the states that the system's energy has. Energy can be transformed but cannot be created or destroyed.

Accordingly, the rate of work done in one cycle and the heat transferred can be expressed under the function,

Substitute 1W for and 1.5 W for

Now calculcate the rate of specific internal energy increase,

The rate of specific internal energy increase is 1.6667W/kg

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
