How is electric potential energy similar to gravitational potential energy? how is it different? where will an electron bound in an atom and have the largest electrical potential energy?

What should the power status of a circuit be when measuring resistance with an ohmmeter?

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?

If the chemical properties of a substance remain unchanged and appearance or shape of a substance changes it is called a ?
