EMARI RILEY HOWE MASS AND HEAT LAB REPORT Purpose The purpose of this lab is to investigate the relationship between the mass of a substance and the amount of heat required to raise the temperature 20°C. By looking at the connection between mass and heat energy, it will help demonstrate why it takes longer to increase the temperature of a substance when more of that substance is present. Background research Heat is an example of thermal and kinetic energy. When there is a difference in temperature heat flows from a warmer object to a cooler one . For example heat flows from a stove ( warmer object ) to a pot ( cooler object ). Heat can be transferred three different ways. The first way is heat conduction which transfers heat by direct touch. An example of this is a child touching a hot radiator. The second way is convection , which recycles cool air/water with warm air/water. An example of this is when a pot of water on a stove has “ bubbles that form on the bottom and rise to the top. Hot water near the bottom of the pan circulates up, forcing cooler water near the surface to sink “ (183). The last way is by Radiation , which uses electromagnetic waves and light to transfer heat. An example of this is when rays from the sun heats up the sand on a beach. Temperature measures the kinetic energy the particles / atoms have in a substance. For each phase , the kinetic energy changes , so we (humans) use thermometers to measure how much energy each phase has .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
