The graph below is called a heating curve. It shows how water changes from one state of matter to another based on temperature and the addition or removal of heat over time. Which point on the graph below represents water changing from a solid to a liquid?

To save time, you can approximate the initial mass of the solid to the nearest ±1 g. for example, if you are asked to add 14.3 g of copper, add between 13 g and 15 g. which of the following sets include two samples with an equal density? which all that apply below 15.4 g gold and 18.7 g silver 15.2 g copper and 50.0 g copper 20.2 g silver and 20.2 g copper 11.2 g gold and 14.9 g gold
