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.
The natural greenhouse effect has been keeping the earth warm for millions of years, allowing life to thrive on this planet. The enhanced or accelerated greenhouse effect, which is what is happening now, is causing global warming and may mean the end of life on earth if we can't slow or stop it.o this  natural greenhouse effect is very useful.    The gases that keep the earth warm are called greenhouse  gases. The most important gas, causing about 75% of the  natural greenhouse effect, is water vapor.
