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.
A greenhouse is a house made of glass. It has glass walls and a glass roof. People grow tomatoes and flowers and other plants in them. A greenhouse stays warm inside, even during winter. Sunlight shines in and warms the plants and air inside. But the heat is trapped by the glass and can't escape. So during the daylight hours, it gets warmer and warmer inside a greenhouse, and stays pretty warm at night too. How is Earth a greenhouse? Earth's atmosphere does the same thing as the greenhouse. Gases in the atmosphere such as carbon dioxide do what the roof of a greenhouse does. During the day, the Sun shines through the atmosphere. Earth's surface warms up in the sunlight. At night, Earth's surface cools, releasing the heat back into the air.
