The conversion of potential energy in coal into the kinetic energy that heats steam is an expression of: answer the first law of thermodynamics the second law of thermodynamics both laws neither law

Let me think about this correct me if I am wrong Laws of thermodynamics 1) Energy cannot be created nor destroyed. It is transferred. 2) All spontaneous reactions will increased the entropy of the universe (More disorder) 3) The entropy of the crystal lattice structure at 0 K is zero PE(coal) --> Steam(K.E) This will increase entropy and also conversion of energy. So BOTH LAWS is my final answer. Wait I would like to use a lifelines I want to phone my Physical chem professor. *Ring Ring* Me: Hello, I wanted to make sure if I got the correct answer. Chem prof: You dont need my help, since you got the right answer. Me: WOOT

your answer is, orbit around the nucleus

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
