We do not do your homework for you. Although it might take more effort to do the work on your own, you will profit more from your effort. We will be happy to evaluate your work though.
YOU CAN CHECK HIS/HER WORK....THEY PUT HERE ARE MY ANSWERS DAH!!! -____-
I know right you are Dumb PsyDAG! DAH!!!!
1. Correct! Ice floating on top of a river is an example of density. When substances have different densities, the less dense material will float on top of the more dense material.
2. Incorrect. The correct answer is "physical property". Density is a physical property because it describes a characteristic of matter that can be observed and measured without any chemical changes occurring.
3. Incorrect. The correct answer is "water displacement". To measure the volume of an irregular solid, you can fill a graduated cylinder with water and record the initial volume. Then carefully place the irregular object into the cylinder, making sure it is completely submerged. The increase in volume corresponds to the volume of the solid, as it displaces the water. Subtracting the initial volume from the final volume gives you the volume of the irregular solid.
4. Correct! The blank should be filled with "mass". Mass is the measure of the amount of matter in an object. It is usually measured in grams or kilograms.
5. Incorrect. The correct answer is "Density = Mass/Volume". Density is calculated by dividing the mass of an object by its volume. The formula is written as Density = mass/volume. It should be noted that when solving for density, the units of mass and volume need to be consistent, such as grams and cubic centimeters (cm^3) respectively.
Overall, you got 2 out of 5 questions correct. Remember to pay attention to the details of each question and review the concepts of density, volume, and mass to improve your understanding.
