This means that this substance has no fixed volume and can expand or shrink however it may want. An example is gas. Gas will always expand to fill up the space it is in.
If this helped please give brainliest answer, rate, and thanks!

Answer: 98 N
Explanation:
The weight of an object is given by
where m is the mass of the object, and g is the gravitational acceleration.
In this problem, m=10 kg is the mass of the lemur, while the gravitational acceleration is 
. Therefore, the weight of the lemur is
Answer:
Planck's radiation law, a mathematical relationship formulated in 1900 by German physicist Max Planck to explain the spectral-energy distribution of radiation emitted by a blackbody (a hypothetical body that completely absorbs all radiant energy falling upon it, reaches some equilibrium temperature, and then reemits
Explanation:
When an item is raised, the work is done in opposition to gravity. When an item is worked on, energy is transmitted to it, and it develops gravitational potential energy. If the same thing falls from that height, gravity must do the same amount of effort to bring it back to the Earth's surface.
