Change Worksheet answer the following questions. The graph was drawn from data collected as a substance was heated at a constant rate. Use the graph to 180 160 Phase Change Diagrarn 140 120 Temperature (°C) 100 D B स 80 60 40 2 4 6 8 16 18 20 22 10 12 14 Tim e (minutes) At point A, the beginning of observations, the substance exists in a solid state. Material in this phase has Deontz_ volume and __ha2_shape. With each passing minute, is added to the substance. This causes the molecules of the substance to me more rapidly which we detect by a t2 Maturise in the substance. At point B, the temperature of the substance is __°C. The solid begins to_A At point C, the substance is completely or in a mate state. Material in this phase has_Det volume and shape. The energy put to the substance between minutes 5 and 9 was used to convert the substance from a 3D This heat energy is called the latent heat of fusion. (An interesting fact.) to a to a Between 9 and 13 minutes, the added energy increases the du of the substance. During the time from point D to point E, the liquid is By point E, the substance is completely in the phase. Material in this phase has volume and shape. The energy put to the substance between minutes 13 and 18 converted the substance from a state. This heat energy is called the latent heat of vaporization. (An interesting fact.) Beyond point E, the substance is still in the phase, but the molecules are moving as indicated by the increasing temperature, Substance Melting point Boiling point Bolognium 20°C 100 °C Which of these three substances was likely used in this Unobtainium 40°C 140 °C phase change experiment? Foosium 70 °C 140°C ONUS: For water, the value for the latent heat of vaporization is 6.8 times greater than the latent heat of fusion. Imagine we were ding heat at a constant rate to a block of ice in a beaker on a hot plate, and it took 4 minutes for the ice to melt completely. How uld it take, after the water started boiling, for the beaker to be completely empty (the liquid water totally converted to water van
