Saying Farewell to Sound

Physics D, F and Honors Physics took their Sound exams today and begin with light and reflection tomorrow. Intro Physics conducted a lab investigation on phase changes. We began talking about phases of matter yesterday and today, examined water undergoing the liquid-solid phase changes. We charted the temperature change of freezing water and melting ice and overlaid the graphs to see that the solid-liquid change (melting) occurred at the same temperate as the liquid-solid transformation (freezing) and that the temperature did not change during the process of changing phase. We'll discuss the lab in class tomorrow as we continue looking at phases of matter and latent heat.
