An unknown substance kept in a sealed container at stp had a density of 808 kg/m3. when the container was opened and the substance was exposed to room temperature, its density became 1.25 kg/m3. which change did the substance most likely undergo?
gas to solid
liquid to solid
gas to liquid
liquid to gas

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

no but i do not usually comment or use my voice that much when it comes to social media

the pseudoscience are like beliefs, theories, or like practices that are considered scientific
