Question

Which of the following will stay constant, no matter if the substance is in the solid, liquid, or gas state? volume shape temperature mass

Answer 1

Answer : The correct option is, Mass

Explanation :

As we know that there are 3 states of matter :

Solid state : It is a state in which the particles are closely packed and does not have any space between them. This state have a definite shape and volume.

Liquid state : It is a state in which the particles are present in random and irregular pattern. The particles are closely arranged but they can move from one place to another. This state have a definite volume but does not have a fixed shape.

Gaseous state : It is a state in which the particles are loosely arranged and have a lot of space between them. This state have indefinite volume as well as shape.

If we are taking 100 grams of ice then after melting its mass remains same but its shape, volume and temperature will be changed and after evaporation its mass remains same but its shape, volume and temperature will be changed.

Hence, the mass will stay constant, no matter if the substance is in the solid, liquid, or gas state.

Answer 2

Answer:

The correct answer is mass

Explanation:

Hello!

Let's solve this!

In the solid state, where the molecules occupy a definite place, and remain still, the shape and volume remain constant.

In the liquid state the molecules take the form of the container that contains them. So the shape is not defined but the volume is defined.

In the gaseous state the molecules are disordered, and have neither defined volume nor shape.

In all three states the mass remains constant.

The temperature causes the change of state.

We conclude that the correct answer is mass
