PLEASE HELP ME ! A group of students performed an experiment in which they dropped a cube of metal into a graduated cylinder of water. The initial temperature of the water was 25 'C. The mass of the water was 50 g
After energy in the form of heat was transferred to the water, its temperature was 35 C. Based on the evidence, how much energy was transferred between the metal and the water?
0.2 cal
10 cal
so call
• 500 cal

How much energy moves onto the next level, in an energy pyramid

Pegmatites are igneous rocks in which the individual minerals are very large. typically, the minerals are all light-colored quartz, feldspar and muscovite. if you were given a black and white photograph of a pegmatite in a quarry (where the rock has been blasted and broken), what physical properties could you use to identify those three minerals in this hypothetical photo? describe each mineral and the specific diagnostic properties. be specific.
