Question

1. draw the particles before and after condensation. what change in stat

Explanation:

Condensation is the process where a gas turns into a liquid. Before condensation (in gas state), particles are far apart, move freely and randomly. After condensation (in liquid state), particles are closer together, have less space between them, and move less freely (vibrate and slide past each other). To draw:

• Before (Gas): Draw a few widely spaced particles (e.g., small circles) with arrows showing random, fast motion, spread out in the left box.
• After (Liquid): Draw more closely packed particles (still small circles, same number as gas to show conservation of matter) with shorter arrows (slower motion), arranged more closely in the right box.

Answer:

Before Condensation (Gas):

Draw widely spaced particles (e.g., small circles) with random, fast - moving arrows, spread throughout the left rectangle.

After Condensation (Liquid):

Draw closely packed particles (same number as gas particles) with slower - moving (shorter arrows) or minimal motion arrows, arranged more densely in the right rectangle.

(Note: The drawing should visually represent the change in particle spacing and motion: gas particles are far apart, liquid particles are closer together.)
