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.
So the Earth's temperature without greenhouse gases would be -17oC.   A:If we didn't have the greenhouse effect, the Earth's average surface temperature would fall way below freezing, and there will be a global ice age, therefore killing off most of the Earth's life forms.     -18C or 0F.
