Science homework help !?

1) Write a sentence that uses both the words "volume" and "meniscus."
2) What units are commonly used to express the volume of a solid?
3) A nugget of gold is placed into a graduated cylinder containing 85 mL of water. After the nugget is added, the water level rises to 225 mL. What is the volume of the gold nugget?
4) Do objects with large masses always have large weights? Provide an explanation for your answer.

1) When measuring VOLUME in a graduated test tube, you must be careful about how you read the measurement, because the MENISCUS can lead to a mis-read.

The MENISCUS is the effect when water's surface tension either makes the water "bulge" up, away from the sides of the test tube, or creates a "concave" depression on the top of the water, where the water "sticks" to the sides of the test tube.

To measure the volume of liquid, you should look at the bottom of the meniscus
