Lamont has a dark container. He knows that the container has a mass of 2.0 g when it is empty. He cannot see inside the container. However, he is able to use a balance to determine that the container has a mass of 2.7 g. What can Lamont conclude about the container?
It contains a solid.
It contains matter.
It contains energy.
It contains a liquid.
I think D.
I mean B
It's B
I agree with San.
It contains matter.
To determine the answer, Lamont needs to reason based on the information given. He knows that the container has a mass of 2.0 g when it is empty and 2.7 g when something is inside it. This indicates that there is an increase in mass when something is added to the container.
Based on this information, Lamont can conclude that the container contains matter, option B. The increase in mass signifies that something is present inside the container, indicating the presence of matter. However, the information given does not provide enough evidence to conclude whether the container contains a solid, liquid, or any specific type of matter.
