Which matter has the highest kinetic energy?
Which matter has the highest kinetic energy? gas particles Does density change with state of matter? Density of a quantity of matter is its mass divided by its volume. External pressure pushes the atoms or molecules closer together and increased temperature usually expands the volume of the material, pushing the molecules apart. A change in […]

Is Mercury a good conductor or bad?
Is Mercury a good conductor or bad? Mercury is the only metal that is liquid at standard conditions for temperature and pressure. Mercury is a poor conductor of heat, but a fair conductor of electricity. Mercury has a unique electron configuration which strongly resists removal of an electron, making it behave similarly to noble gas […]
