What is its density? Density = mass / volume = 15 grams / 10 milliliters = 1.5 gm/ml. Density is also useful in determining if an object will float on water. The density of water is approximately 1 gram/ml. If an object’s density is greater than that of water, it will sink. If an object’s density is …

Density of water — Ice is less dense than water and therefore floats on water. If ice sank, life in lakes and rivers would be very different if it existed at all. Cohesion, adhesion, and capillary action — Water is moved throughout plants by capillary action, adhesion/cohesion, root pressure, and transpiration.

The mass, volume, and density were found of Trial 7. Trial Number Mass of Biodiesel Volume of Biodiesel Density of Biodiesel 7 1.7458 g 1.9 mL .919 g/mL While doing research on biodiesel, the density was found to be .903 g/mL (Sarma). The density of soybean oil was also figured out to be .8054 g/mL, so obviously some form of reaction took place.

Jun 09, 2011 · Fact: Water expands on freezing, thus ice has a larger volume than the same mass of liquid water, which explains why ice floats in water. In general, matter expands when heated and contracts when cooled, but water behaves differently. For a fixed mass of water, its volume is lowest and its density is highest at 40C.
