Answer the following question given this paragraph: A golf ball and a table tennis ball are about the same size. However, the golf ball is much heavier than the table tennis ball. Now imagine a similar size ball made out of lead. That would be very heavy indeed! What are we comparing? By comparing the mass of an object relative to its size, we are studying a property called density. Density is the ratio of the mass of an object to its volume. Q: Which property can you study by comparing the mass of an object relative to its size? Choices: - volume - weight - motion - density A:
density
