- When a powdered drink mix was added to water, the liquid turned orange. A student decided the taste was too strong, so he poured out half of the liquid and added more water. Which of the following most likely occurred when more water was added?
- A student adds 10 grams of lour different powdered beakers. The student then adds 100 mL of water to each beaker, stirs the mixtures, and allows them to sit for half an hour before recording observations. Which question is the student most likely trying to answer with this investigation?
- A student combined powdered paint with water to make a small amount of blue liquid paint. The student left the paint mixture in an open container. Several days later the student found the container and observed that changes had occurred. What most likely happened to the mixture?
- A beaker with 115 mL of solution has a temperature of 21 degrees Celsius. The solution contains 5 g of salt and 115 mL of water. Students added two ice cubes to the solution and stirred the solution with a stirring rod. Which properties of the solution changed as the ice cubes melted?
