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.
1 Earth's atmosphere naturally has greenhouse gases in it. Without them Earth would only be heated by its core and the rays of the sun. Those rays would warm us during the day, but at night all the heat would be lost back into space.  Greenhouse gases insulate Earth, comparable with a blanket.
