What are some everyday examples of equilibrium?

Equilibrium is achieved if all the forces acting on an object are balanced. There are various types of equilibrium depending on whether the context is physical, chemical or biological.

A car at a constant velocity is at equilibrium as well, since the force of friction is balanced by the force from the car's engine. When hot coffee cools down to room temperature, it is said to attain thermal equilibrium with the room since the amoun..

How does a bird urinate?

The mammalian urination system consists of kidneys, a bladder and a urinary tract. Mammals use water to convert ammonia to urea, which is stored in the bladder until it can be excreted as urine. Most birds and reptiles do not have a bladder, so their kidneys and lower gastrointestinal tract work together to keep electrolytes stable. The uric acid is mixed with feces in the coprodeum, which turns it into a thick, white paste before being excreted. This system works well at minimizing water waste as well as keeping the bird light enough for flight.\nUric acid can be corrosive, which is why it is..
