When a solid sample was heated, its temperature increased but it did not melt. What has happenedto the average molecular kinetic energies of the atoms in the sample and why?A Kinetic energy remained the same because potential energy decreasedB Kinetic energy remained the same because potential energy increasedC Kinetic energy decreased because the temperature increasedD Kinetic energy increased because the temperature increasedA spoon, a fork, and a knife are stacked on top of each other overnight. The temperature of both thefork and spoon is 21°C the next morning. According to thermal equilibrium, what can be predictedabout the temperature of the knife?A The temperature of the knife is also 21°C because equilibrium has been reached between allthree objects.B The temperature of the knife could only be determined through measurement.C The temperature of the spoon and fork are both conducted to the knife giving it a resultingtemperature of 42°C.D The temperature of the knife would be 14°C because the knife represents roughly one third ofthe overall mass.Automatic Zoom

Temperature increased so average molecular kinetic energy also increased.
