Most hydrometers measure the specific gravity of samples: in simple terms, a hydrometer tells the user if a liquid is denser or less dense than water. It will float higher in a liquid with a greater specific gravity, such as water with sugar dissolved, compared to one with a lo...
Colder gasoline is more dense than warmer gasoline, so another way to look at it is that a cold gallon of gas contains more energy than a warm gallon of gas, even though they might cost the same. And that's why this theory appeals to the budget-conscious among us. Even though the ...

squeezed out of the mud and may move into sandy layers nearby.Over long periods of time (millions of years), accumulations of gas and oil can collect in the sandy layers.Both oil and gas are less dense than water, so they generally tend to rise upward through water-saturated rock and ...
Mercury measures 13.534 grams per cubic centimeter. That's thirteen and a half times more dense than water, which scientists have assigned a density of 1.0. What Is Density? Density is the measurement of an object's mass divided by its volume. Density cannot be measured directly; instead, a...
