Fluorine-21 has a half life of approximately 5 seconds. What mass of 3.0 mg 1 point will remain after 25 seconds.

The most efficient way to establish the best possible economizer position is to measure

Temperature is _related to the average kinetic energy of a gas. inversely directly not disproportionally

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
