The table shows the methods two groups use to dissolve sugar in water. Group X Group Y measure 10 grams of sugar measure 5 grams of sugar heat a pot with 100 mL of water to 105°C heat a pot with 50 mL of water to 70°C add the sugar to the water with a spoon add the sugar to the water with a cup stir gently stir gently record the time it takes to fully dissolve record the time it takes to fully dissolve Which group will most likely dissolve the sugar the fastest, and why? A group X because they used more water B group Y because they used less sugar C group X because they heated the water more D group Y because they added the sugar with a cup

You are a researcher for a golf club manufacturer. you are given two identical looking cubes of a metal alloy. you are informed that they are made of the exact same material, but one is crystalline, whereas the other is amorphous. it is your job to determine which one is amorphous this one is more stress-resistant and is useful in reinforcing golf clubs. which of the following is the best way to determine which is which? a. determine the density of each cube. the more dense one is the amorphous solid. b. melt both cubes and look for a broader range of melting temperatures. the one that melts over a broader range of temperatures is the amorphous solid. c. determine the density of each cube. the less dense cube is the amorphous solid. d. melt both cubes and measure the range of melting temperatures. the one that melts over a narrower range of temperatures is the amorphous solid.
