Bharti carried out an experiment to see the effect of temperature on a saturated solution. She took 100 g of water in two beakers. She then dissolved sugar in one and salt in the other slowly by adding small amounts each time and stirring, until the solution became saturated. The temperature of the solution was maintained at 20 °C. She repeated the same experiment at 60 °Cand 100 "C. This is what she observed.

He drops the sugar cubes at the same time and then observes how much of them dissolves in two minutes. What will be the result of Sam’s experiment, and which statement should he use as his conclusion? A A greater amount of sugar dissolved in hot water because temperature is directly proportional to the solubility rate of sugar in water. B Temperature does not affect the solubility rate of the sugar cube in water because sugar dissolves equally in both cold and hot water. C A greater amount of sugar dissolved in hot water because temperature is inversely proportional to the solubility rate of sugar in water. D A smaller amount of sugar dissolved in cold water because temperature is inversely proportional to the solubility rate of sugar in water.Jollibee Burger Item Sodium(mg) Fat(g) Calories Item cost($) Beef Patty 50 17 220 $0.25 Bun 330 9 260 $0.15 Cheese 310 6 70 $0.10 Onions 1 2 10 $0.09 Pickles 260 0 ,. 5 $0.03 Lettuce 3 0 4 $0.04 Ketchup 160 0 20…
