Describe the interaction that occurs between two objects with the same electrical charge.

The human eye contains a molecule called 11-cis-retinal that changes shape when struck with light of sufficient energy. the change in shape triggers a series of events that results in an electrical signal being sent to the brain that results in vision. the minimum energy required to change the conformation of 11-cis-retinal within the eye is about 164 kj/mol.

If two objects at different te,peraure are in contact with each other what happens to their temperature
