Which one of the following statements regarding matter is not correct ?
Explanation
Matter is defined as anything that has mass and occupies space [t4]. It exists in four fundamental states: solid, liquid, gas, and plasma. Plasma is formed at extremely high temperatures when atoms are ionized, causing electrons to be stripped from their nuclei [c1][t2][t4]. Colloids are mixtures where the dispersed particles are larger than individual atoms or small molecules (typically 1 to 1000 nanometers) but smaller than those in suspensions [t1][t6][t7]. Statement 3 is incorrect because matter is composed of 'extremely small' particles, not 'large' particles [c3][c5]. While atoms and molecules are the constituent units of matter, they are microscopic and cannot be seen even with an ordinary microscope [c2][c5]. The term 'large' is scientifically inaccurate when describing the fundamental building blocks of matter compared to macroscopic objects or even colloidal particles.
