Write a hypothesis for part i of the lab, which is about the effect of mass on the ability of an object to absorb or release thermal energy. use the format of "if . . then . . because . .” and be sure to answer this part of the lesson question: "how does mass affect thermal energy transfer? ”

sample response: different masses will change temperature at different rates when exposed to the same amount of thermal energy. this is because the amount of mass affects an object’s ability to absorb thermal energy.

invention of the washing machine

in the past, people used sticks and stones or scrub boards to clean their clothing. as it was sweaty, backbreaking work, we owe a world of to james king because he created the model for the modern washing machine in 1851. the most important issue was that this machine cleaned clothes while a person cranked the handle. doing this made people who used it develop strong muscles in their arms. later, in 1908, alva j. fisher created an electric washing machine named thor. this one was not the first automatic washing machine. however, it was one of the most popular models at the time.
