Searches related to Two identical beakers with exactly the same amount of warm water were prepared. Th e first beaker was allowed to cool by sitting in a classroom with an air temperature of 233 degrees C. The second beaker was placed in a large bucket of ice water at 0 degrees C. The temperature of each was measured every minute for 45 minutes. Which beaker of water starts off at higher temperature?

C) electrons encircling a nucleus with neutrons and protons

Well technically there are two correct answers b and d. but for you its probably b in general.good day sir/ma'am : ) (i know not gender)

Vander waals forces are inter molecular bonds that exist within molecules of the same substance. a water molecule is made up of oxygen and hydrogen atoms which share electrons between each other. the vander waals forces are forces that exist between multitude of different  molecules of water. dipole dipole forces is the type of vander waals force that exist in water. the oxygen atom which is more electronegative pulls the shared electron closer to itself thus generating a partial negative charge while the hydrogen acquire a partial positive charge. these two different charges causes attraction to occur in water molecules.
