In this lab, we will focus on the ways heat is transferred. source data for performing necessary calculations. Air flows through a heating element and heat lost by an egg placed inside. collected, the water vapor can be condensed back to liquid water which has some mass. No exchange of boiling water is an open system it exchanges heat with the air around it and water vapor. Remember: Lab notes must be taken. you could most likely come up with a container that would maintain the egg's temperature almost the fluid or at its boundaries. energy in form of heat but the amount of liquid within does not change. Your container is a thermodynamic system a part of the Universe separated from the Keeping careful notes is an essential component of all scientific practice. Click on the Tools tab from from the top of the Arduino IDE. systems and isolated systems. The Reaumur scale is a temperature scale that was used widely in Europe in the 18th and 19th centuries.
