Geometry and Eratosthenes In Professor Russ physical science class, there’s a plethora of subjects you, as a student, are bound to cover. This semester we had discuss over twenty different fields of science; the first being Geometry and Eratosthenes computing circumference of earth. We started the final semester off with two worksheets. The first was the “Angles of a Triangle”, we had to cut out the three angles of the triangle and piece them together in a shape. The three angles form a straight line; which led us to theorize that when you take three angles of a triangle and put them together they form a straight line. After the Angles of Triangle assignment, the next was parallel line cut out exercise. From this assignment we learned that equal angles should fit together, …show more content…
This led us to talk about Thermal energy and its many uses. Before there was thermal energy, there was the Caloric theory. The caloric theory stated that all gas was a liquid. Yet, when Rumford came along he theorize that heat was a motion. Thus the birth and definition of thermal energy was brought into existence. Thermal energy is the vibration or mater that move rapidly making the vibrations bigger and it all hotter. Thermal energy works in three ways; convection, conduction, and radiation. Convection is hot air or liquid moving to connect with a cooler body and heating it. An example of convection is the room and radiator heating process. The radiator lets out heat which rises and sucks the cool air down turning it into heat. The same happens with prevailing winds and rain; the equator pushes the heat up while the cold winds from the northern and southern part of globe go down to the equator. While the hot air is up in the atmosphere it gets really cold and wet which causes rain. Conduction is the direct contact of hot body with cooler body. Radiation is a hot body emitting electro- magnetic radiation which moves to a cooler body and heats
