En un experimento como el de Boyle se tiene un gas en un recipiente en forma de J. Se le añade un líquido cuyo volumen inicial es de 7 litros (7 lts), lo cual ocasiona una presión de
2 atmosferas (2 atm) en el gas. ¿Cuál será el volumen de líquido que tendríamos que usar
si queremos incrementar la presión del gas a 3 atm? Considera que todo el experimento
se lleva a cabo con temperatura constante y con la misma cantidad de gas.

The answers is bad germs in their

Density and pressure

A. ​it generates energy from carbohydrates.b. it requires activation by oxygen.​c. ​it is used by cells to dispose of excess electrons

Vander waals forces are inter molecular bonds that exist within molecules of the same substance. a water molecule is made up of oxygen and hydrogen atoms which share electrons between each other. the vander waals forces are forces that exist between multitude of different  molecules of water. dipole dipole forces is the type of vander waals force that exist in water. the oxygen atom which is more electronegative pulls the shared electron closer to itself thus generating a partial negative charge while the hydrogen acquire a partial positive charge. these two different charges causes attraction to occur in water molecules.
