Here it states, which of the following statements deals with potential energy without non-chemical energy associated with it. Remember, potential energy is just the energy of position, whereas chemical energy, which is an offshoot of potential energy, is just associated with the chemical bonds of atoms. Alright. So if we take a look here, it says a car traveling with a velocity of 51 meters per second with a mass of 1,250 kilograms. Here we're talking about velocity, we're talking about the motion of this car, so this is more associated with kinetic energy. So, this is out.
Next, your chemistry book sitting on a table counter near the trash can, weighing 12 newtons at a height of 1.2 meters. So make sure it doesn't fall into the trash can. Here, they're just talking about the position of the chemistry book. It's at a certain height, and we're talking about a force on it. Here, this is purely potential energy, so this would be our answer. But let's look at the other options.
A chunk of coal being thrown into a furnace to generate heat. Here we're talking about heat being generated from this. This is closely related to thermal energy. And then next, we have the warmth coming from a campfire. So again, we're talking about temperature, we're talking about heat. So this is a version of kinetic energy in the form of thermal energy.
So, out of all the choices, the only one that is purely potential energy without talking about chemical energy would have to be option B.
