A scuba tank is filled with a mixture of three gases (argon, nitrogen and oxygen) as total pressure of 490 kPa If the partial pressure of argon is 5 kPa and
nitrogen is 225 kPa, What is the pressure of oxygen in the tank? *

petroleum? coal maybe?

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
