C
Explanation:
The question was, "Does temperature of water affect the amount of copper sulphate water will dissolve?" C says, "Establish two different temperatures if water and test how much copper sulphate will dissolve at each temperature." The bold words/phrases are key words/phrases that I found in both. I also don't know why I've been asked this question on a quiz if it's for high school. I'm in 7th grade. Weird
