Answer:

Because of the high permeability and high saturation level of holding magnetism.

Explanation:

Soft iron always used in the core of an electromagnet because of the following reason which are discussed below.

  • Permeability: These magnets are highly permeable means they can gain magnetism when current is passes through them and instantly loose magnetism after removal of current.
  • High saturation level: The property of these soft magnets are they have the high value of saturation means they can hold high level of magnetism without easily saturating.

if 162.4 j of heat are added to a gas contained within a cylinder and the gas expands, doing 87.3 j of work, what is the change
labwork [276]

The changes in internal energy of the system <u>75.1 J.</u>

The internal energy of a thermodynamic system is the total energy contained in it. It is the energy required to create or prepare a system in a given internal state and includes contributions of potential energy and internal kinetic energy.

Calculation:

Internal energy =  162.4 j - work done

                        =  162.4 j - 87.3 j

                         =<u> 75.1 J</u>

<u />

Internal energy, in thermodynamics, is the property or state function that defines the energy of matter in the absence of capillary action or external electric, magnetic, or other fields.

Internal energy is the microscopic energy contained in the matter given by the random and disordered kinetic energy of the molecules. It also includes the potential energy between these molecules and the nuclear energy contained in the atoms of these molecules.
