Question

which is the correct order of the different phases of matter from highest kinetic energy (ke) to lowest kinetic energy
freezing, melting, boiling and
condensation
plasma, gas, liquid and solid
solid, liquid, gas and plasma

Explanation:

Step1: Recall Kinetic Energy in Phases

Kinetic energy (KE) is related to particle movement. In plasma, particles have high energy and move freely. Gas particles also move freely but have less energy than plasma. Liquid particles have more restricted movement (lower KE than gas), and solid particles vibrate in fixed positions (lowest KE).

Step2: Analyze Options

• First option: Freezing, Melting, Boiling and Condensation are phase - change processes, not phases of matter.
• Second option: Plasma (highest KE as particles are ionized and move freely), gas (particles move freely but less energy than plasma), liquid (particles have some movement but are more closely packed), solid (particles vibrate in place - lowest KE) is the correct order of phases from highest to lowest KE.
• Third option: Solid, Liquid, Gas and Plasma is the reverse order of KE (should be from lowest to highest if we consider this sequence without reversing, but the question asks highest to lowest).

Answer:

Plasma, Gas, Liquid and Solid
