What symbol is used to represent internal energy in the first law of thermodynamics?

a. q
b. w
c. u
d. v

\Delta U = Q - W

aka—^

(ΔU = Q − W)

The symbol for Internal Energy Change isΔU. It is the sum of all the microscopic energies such as: translational kinetic energy. vibrational and rotational kinetic energy.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
