Einstein used the photoelectric effect to show that light can behave both as a particle and as a wave.
Use the ideal gas equation PV=nRT. You can compare before and after using P1V1/n1T1=P2V2/n2T2. Since the number of moles remains constant you can disregard moles from the equation and use pressure, volume and temp. Make sure your pressure is converted to atmospheres, your volume is in liters, and your temperature is in kelvins.
It would be 6 because of the elements
Energy released from cell respiration is know as ATP
