Can thermal energy change
WebTwo objects with different temperatures can exchange energy, if they are in thermal contact . The energy exchanged between objects because they are in thermal contact is called heat . If two objects are in thermal contact and do not exchange heat, then they are in thermal equilibrium. WebStudents will explore energy changes during chemical reactions, heat of reaction (ΔH), and the connection between energy changes and chemical changes. Safety. Be sure you and the students wear properly fitting goggles. Acetic acid (vinegar) vapors can be irritating. Work in a well-ventilated area. In the event of eye contact, flush with water.
