Which statement regarding weight in matter is true?

The assertion that all matter has weight is fundamentally accurate because weight is a measure of the gravitational force exerted on an object due to its mass. This applies universally to all states of matter, including solids, liquids, and gases. Regardless of the form it takes, as long as matter has mass, it will possess weight when subjected to the force of gravity.

This principle is rooted in physics, where weight is defined as the product of mass and the acceleration due to gravity. Each type of matter has a specific mass, and hence, it can be said to have weight, which allows us to quantify it.

The other statements do not hold true universally for all types of matter. For example, weight being dependent on temperature is not accurate since weight remains constant in a gravitational field, irrespective of temperature. Additionally, the idea that only solids have weight overlooks liquids and gases that also possess weight based on their mass. Lastly, weight is indeed a relevant factor in discussions of matter, as it is directly linked to mass and affects various physical properties; thus, dismissing weight as irrelevant would not align with scientific principles.
