Question

Yolanda makes this hypothesis: "If salt is added to water, then the water will boil at a lower temperature." She sets up and experiment to test her hypothesis, but discovers that it actually takes more heat to bring the saltwater to the boiling temperature. Her lab partner, Kevin says" Your hypothesis was wrong--no good at all!"

DO YOU AGREE OR DISAGREE WITH KEVIN AND WHY???
