Rita conducted an experiment which involved placing a thermometer in each of four identical beakers
containing four unknown liquids, each of equal volume. All four beakers had just been removed from an oven
maintained at 92 degrees Celsius (°C) where they had been for the previous one hour. They were placed on a
lab table in a room that was maintained at a constant 22°C. Rita recorded the temperatures read on the four
thermometers every 15 minutes (min.) for one hour. The data collected is in the following table:

matter This matter collapses onto itself, extinguishing the star and resulting in the black
hole

core collapsing in on itself. This is due to gravitational forces that act without nuclear
fusion counteracting them

normally produced in stars emitting large amounts of electromagnetic energy
