Battery voltage reacts highly to charging and discharging. As a battery is charged the indicated voltage increases and, as discharging occurs, the indicated voltage decreases. With experience, one can accurately determine state of charge using a voltmeter. Percentage of Charge 12 Volt Battery Voltage Specific Gravity 100 12.70 1.265
Yes-- without the Green House Effect, Earth's avg temperature would be 60 degrees F cooler, and our oceans would be frozen. You would freeze. The earth would be pretty well frâ¦ozen over. The average surface temperature would be about -4 degrees Fahrenheit if there were no greenhouse effect.
This is an artist's impression of what Earth looked like 4 billion years ago. The planet has no oxygen in its atmosphere and no ozone layer, so poisonous ultraviolet rays from the Sun hit the surface directly. The molten centre of the planet is still extremely hot, and volcanoes erupt constantly, forming the mountains and landscapes of the planet.
