Introduction to Chemistry
A sample is found to be slightly compressible and has a definite volume, but indefinite shape.
The sample is most likely a

True
When elements combine to form compounds, those compounds have the properties that are
completely different from those of the elements from which they were made.
True
Charles' Law states that the volume of a given amount of gas will increase if the temperature
of the gas is increased.
