Project : Thermal Energy Transfer
Storyboard Text
- Also catalyst means a substance that speeds up a chemical reaction, or lowers the temperature or pressure needed to start one, without itself being consumed during the reaction. And misconception means a view or opinion that is incorrect
- And Exothermic reactions mean reactions that release energy into the environment
- Today we are going to talk about two Thermal Energy transfer are Endothermic reactionsand Exothermic reactions
- Endothermic reactions means the absorption of heat and is the opposite of Exothermic reactions
- One example of Endothermic reaction Converting frost to water vapor (melting, boiling, and evaporation, in general, are endothermic processes
- One example of exothermic reactions is Making an ice cube. Making ice cube is a process of liquid changing its state to solid
- All chemical reactions involve the transfer of energy. Endothermic processes require an input of energy to proceed and are signified by a positive change in enthalpy. Exothermic processes release energy upon completion
- catalyst endothermic is heating it up
- catalyst exothermic is cooling it down
- one misconception of Thermal Energy is Cold items have no Thermal Energy because All matter has thermal energy, even matter that feels cold. That's because the particles of all matter are in constant motion and have kinetic energy.
