A sample of helium has a volume of 514 mL at 410 K. The sample is cooled at constant pressure to a volume of 356 mL. What is the new temperature?

Variables,control,conclusion and finally scientific theory

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
