Modern vacuum pumps make it easy to attain pressures of the order of 10⁻¹³ atm in the laboratory. a) at a pressure of 8.65×10⁻¹⁴ atm and an ordinary temperature of 296.0 k , how many molecules are present in a volume of 1.07 cm³? n= ? moleculesb) how many molecules would be present at the same temperature but at 1.06 atm instead? n=? molecules

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
