Answer: It can be written as: V = nRT/P. "P" is pressure, "V" is volume, n is the number of moles of a gas, "R" is the molar gas constant and "T" is temperature. Record the molar gas constant "R". R = 8.314472 J/mole x K.
Explanation: That the answer
The correct answer is 2. Magnetic fields must start at the north pole of a magnet and end at the south pole of a magnet. I took the test. Hope I helped!
