You would weigh it on your kitchen scale
Yes, the mass of the sealed cup of water would remain the same as long as no water is added or removed from the cup. The mass is a measure of the amount of matter in the system, which would not change in a sealed environment.
use a measuring cup
A cup of water and a cup of ice would have the same volume and mass because they fill the cup to the same level. However, the cup of ice would have a lower density than the cup of water because ice is less dense than liquid water due to its expanded crystal structure.
The mass is extremely similar. Also note, different brands of whiskey would also have slightly different mass.
Since oil will float on top of water, we can assume that the weight (or mass) of water is greater than that of oil.
The answer will depend on the size of the cup and, therefore, the quantity of water in it!
You can use a scale to measure the mass of both cups of water and then compare the readings. Make sure to tare the scale with an empty cup before measuring each sample. Be cautious with the handling of salt water, as it can corrode certain types of scales.
James wants to find out whether a cup of salt water or a cup of fresh water will freeze more quickly. What is the best way for him to determine this

First, measure the mass of the water in the bathtub using a scale. Next, immerse yourself completely in the water and measure the increase in water level using a measuring cup. This increase in volume of water displaced is equal to your body volume. Finally, apply Archimedes' principle which states that the buoyant force acting on an object is equal to the weight of the water displaced, to calculate your mass.
They are virtually the same
You would use a measuring cup or a graduated cylinder to measure the capacity of a container. Fill the container with water and then pour the water into the measuring cup or graduated cylinder to determine its volume.
