The table provides data for two CH3OH(l) samples. Based on this information, which of the following statements describes what happens when these samples are initially mixed, and why?Sample 12Initial Volume (mL) 125.0250.0Initial Temperature (°C) 36.018.0a. Thermal energy is transferred between the CH3OH molecules in sample 1 and the CH3OH molecules in sample 2 because both samples contain the same substance.b. The CH3OH molecules from sample 2 transfer thermal energy to the CH3OH molecules from sample 1 through collisions because there are more moles of molecules in sample 2.c. The CH3OH molecules from sample 1 transfer thermal energy to the CH3OH molecules from sample 2 through collisions because sample 1 has a higher density.d. The CH3OH molecules from sample 1 transfer thermal energy to the CH3OH molecules from sample 2 through collisions because the average kinetic energy of the molecules in sample 1 is greater.
