Participants in the RFS2 use the EPA Moderated Transaction System (EMTS) to submit transactions. EMTS incorporates features that help establish a well-functioning and transparent market for RINs. The EMTS data flow supports the reporting of all RIN transactions including the generation, separation, purchase and sale, and retirement of RINs.
The heating and cooling of air and water are essential parts of our everyday lives, supporting our comfort, safety, and productivity. However, these services come at a cost, with approximately 44% of energy consumption in the United States directly attributable to heating and cooling.
Heating curves show how the temperature changes as a substance is heated up. Cooling curves are the opposite. They show how the temperature changes as a substance is cooled down. Just like heating curves, cooling curves have horizontal flat parts where the state changes from gas to liquid, or from liquid to solid. You are likely to have used salol or stearic acid in a school practical lesson to make your own cooling curve.
