If a substance has a large mass and a small volume what can you conclude about it

19. at high pressures, how does the volume of a real gas compare with the volume of an ideal gas under the same conditions, and why? eman- it is much less because real gas partides are not moving. there is no difference because the gas laws are always obeyed. it is much less because at high pressures the temperature drops. it is much greater because real gas partides take up space.

Theoretically, which metal should be the most reactive? hydrogen lithium francium fluorine

Which is mostly likely why many scientists reject the cold fusion theory
