Cockerels (like those abve) call in the morning according to the social hierarchy of the flock, with the most dominant male crowing first, according to a study.
A low-precision gravimetric titration can achieve 10,000.the same. reproducibility as a titration with a 50 mL volumetric buret. It requires less reagent quantities, it is faster and less. complicated titration for the students and the teacher, and the equipment. is far less expensive.
Boyle's Law. Kinetic molecular theory says that, when you confine molecules to a smaller space, they collide more with inner walls of their container, applying more pressure. So pressure and volume have an inverse relationship. Obtain a plastic syringe from a pharmacy. Push the plunger in to just where the markings start, and seal the hole with duct tape.
