You perform an experiment, where you placed a 1 kg piece of metal on a vibrating plate. You increased the vibration frequency by 5 hertz every 2 minutes and then measured the temperature of the metal that resulted. The data below represents your results. Graph the data using Excel as we discussed in class and pick the graph that best represents the trend of this data.

Linear relationship where temperature of metal increases in a linear fashion as the vibration frequency increases.
