Explain the method applied for determining the density of a solid (Regular and inregular) and liquid.
Answers
Answer:
Here is your answer
Step-by-step explanation:
Density is a measure of how compact the mass in a substance or object is. The density of an object or substance can be calculated from this equation: density in kilograms per meter cubed is equal to mass in kilograms, divided by volume in meters cubed (p = m / v). So density could be described as the number of kilograms that 1 meter cubed of substance weighs.
When two materials are mixed together, the density is what determines which one will rise and which one will sink. This tells you whether objects sink or float and explains why cold fronts sink below warm fronts in weather patterns. Understanding density is an important step in understanding the world around us.
Calculating Density of Solids or Liquids
When you're asked to calculate density, you need to use a combination of the density equation we've already introduced and an understanding of volume. For example, you might not be given the actual volume of the material or object to put into the density equation. Instead, you may be given the measurements of the object and be expected to figure out the volume yourself.
The volume of a cube or cuboid is length times width times height (L * W * H). So if you needed to calculate the density of a cube, you would first measure the length of one of the sides. Let's say that the length of our cube turned out to be 3 meters. You would first need to calculate the volume by multiplying 3 by 3 by 3 (V = 3 * 3 * 3). You would also need to put the cube on a scale to measure its mass. Last of all, you would divide your volume by your mass to get the density of the cube (p = m / v).
But what if the material isn't a solid? What if it's a liquid?
Measuring the volume of a liquid isn't as obvious, because liquids change shape. When you measure liquids in a measuring jug, the numbers on the side are things like fluid ounces, pints, and liters (or milliliters). Liters are used in scientific equipment because those are standard scientific units. And there's a very good reason we use liters. Volume is measured in meters cubed, and 1 meter cubed is equal to 1,000 liters. So the conversion is super easy. (Also note that 1 liter is equal to 1,000 milliliters).
So to summarize, here are the steps to calculate the density of a solid or liquid:
1. Figure out the volume, by either measuring the dimensions of a solid or using a measuring jug for a liquid. Convert any units as needed to get a number in meters cubed.
2. Put the object or material on a scale and figure out its mass.
3. Divide the mass by the volume to figure out the density (p = m / v).
