Choose the correct statement below. Choose one: Condensing steam to water is endothermic, and freezing water to ice is endothermic. Condensing steam to water is exothermic, and freezing water to ice is endothermic. Condensing steam to water is endothermic, and freezing water to ice is exothermic. O Condensing steam to water is exothermic, and freezing water to ice is exothermic.

In the above image, you have a solid at less than 0 oC. As you add heat (Q), the temperature of the solid increases until it hits a point when it would start melting. In the case of water, this is at 0 oC. Notice that at this point the temperature stops rising and we have a mixture of solid/liquid. We are still adding heat but the temperature is not changing. Once all of our solid becomes liquid, the temperature starts to rise again until it hits another plateau, at 100 oC. This is the point where the water boils and starts becoming a gas. Again, we add heat but the liquid/gas mixtures temperature does not change. Once all the liquid has become gas, the temperature will start to rise again. Is it possible to have 0 oC water and 0 oC ice?   Yes or No?

The heat of fusion for water is 334 J/g. How much heat energy is involved in the melting of 174.2 g of ice? Heat of Fusion: Q=H(fus) x m.

What change in energy is required to heat 55.00 g of water at 15.00 0C to vapor at 180.0 0C?
