When observing a very small piece of dust in a liquid under a microscope, the dust appears to jiggle slightly. This movement results from the dust interacting with the
molecules in the liquid. What property of the molecules in the liquid causes this effect?

What amount of heat is exchanged when 106.2 grams of substance y goes from a liquid at 35 degrees celsius to a solid at the same temperature? melting point of substance y = 35 degrees c; δhvaporization = 3.67 j/mol; δhfusion = 3.30 j/mol. mwsubstance y = 28.22 g/mol. −12.4 j −3.51 x 102 j 1.24 x 101 j 351 j
