Chemistry States Of Matter Level 2 Activity For Kids Primaryleap Co Uk The phase diagram for water is shown in the figure below. figure 13.20.1 13.20. 1: phase diagram for water. notice one key difference between last section's general phase diagram, and the above phase diagram for water: in water's diagram, the slope of the line between the solid and liquid states is negative rather than positive. The 3 types of phase changes for water are: evaporation: when water is in a liquid state, it can evaporate into a gas or freeze into a solid. melting: if water is in a frozen state then you add heat, it melts and turns into a liquid again. condensation: when water vapor in the air condenses, it turns back into a liquid such as in the form of rain.
Triple Point Of Water The Temperature Where All Three Phases Coexist Phase change diagram. heating curve. a common form of depicting the temperature at which a substance changes states and also how much heat is required to change state is a heating curve. the heating curve for water is shown below. note that at the point in which the liquid changes state there is no change in temperature. A phase diagram is a graphical representation of a substance's physical states under various temperature and pressure conditions. pressure is on the y axis of a typical phase diagram, and temperature is on the x axis. a phase change occurs when we cross the lines or curves on the phase diagram. Phase stability. earlier in the morning, the droplets of water in figure 7.5.1 7.5. 1 were tiny crystals of ice, but even though the air temperature is still around 0°c and will remain so all day, the sun's warmth has rendered them into liquid form, bound up by surface tension into reflective spheres. States of matter. by heating or cooling a substance, its state can be changed. liquid one of the three states of matter. liquids, like water or oil, do not have a fixed shape and can flow. solid.
