In the lab, we determined the amount of energy transferred from the coal to the water. Why would this be considered an open system?
The chemical potential energy was transformed to heat.
Heat flows from the coal to the water and no energy is lost.
No heat or matter was transferred to the water.
Some of the heat from the burning coal was lost to the surroundings.
The image shows energy flowing from coal, to a coal-fired power plant, to a power tower, and finally to a radio. Pick the correct order for the types of energy as they are converted from one type to the other in each stage of the process.
Electrical Energy --> Thermal Energy--> Chemical Potential Energy--> Sound Energy
Thermal Energy --> Chemical Potential Energy--> Electrical Energy--> Sound Energy
Chemical Potential Energy --> Thermal Energy--> Electrical Energy--> Sound Energy
Sound Energy --> Thermal Energy--> Chemical Potential Energy--> Electrical Energy
