STAAR 2013 #14; RC 1; Supporting; 47. 1. A student measures the temperature of water being heated on a hot plate. The student observes that the temperature of the water is 53ºC. How many more degrees Celsius must the temperature rise before it reaches the boiling temperature of water?. The heating curve is a graph which represents how a sample changes phases. As heat is added over time, the sample changes temperature and phase accordingly. Thus . heating . curve.. Using a full sheet of paper, make a large scale drawing of this diagram.. What is the Matter?. Stuff of which all materials are made out of. Anything that has mass and takes up space. .. WHY ARE WE CONCERNED WITH MATTER??. Chemistry is the science concerned with the properties, composition, and behaviour of matter!. Do Now: Water boils at _____torr, ____1atm, _______mm Hg, ______kPa . Review: . Name the phase change.

You've no doubt experienced chocolate melting on a hot day, so let's do some experiments to recreate these conditions as well as a few others before comparing results and coming to some conclusions.. I know parents are very busy and totally understand this may not be an option for your family.. If this is the case- I have included a video that your child could watch instead completing the experiment. .
