Which is the best example of potential energy?

Which is the best term to use when describing the energy of motion?

In a chemical reaction occurring in an open beaker, the reactants have a mass of 10.0 g and contain 1000 J of energy. The products in the beaker contain a mass of 5.0 g and 500 J of energy. Which best explains the difference in energy and mass as reactants are converted to products?

Thermal energy is the energy associated with

Which statement is correct about the law of conservation of energy?

What best identifies the energy transformation that occurs in the flashbulb?

According to the law of conservation of energy, what will most likely happen in a closed system?

Which energy change best relates to a boulder that is rolling down the side of a hill?

Chemical energy in burning wood is changed into thermal energy. The thermal energy is absorbed by water, which boils to produce steam. The thermal energy is changed into kinetic energy in the moving steam. The kinetic energy is used to turn a turbine, which converts the kinetic energy into electricity. Which sentence best describes this system?

Which statement describes thermal energy?

Reactant X contains 199.3 J of chemical energy. Reactant Y contains 272.3 J of chemical energy. Product W contains 41.9 J of chemical energy. If the reaction loses 111.6 J of chemical energy as it proceeds, how much chemical energy must product Z contain?
