Question

1. No color (clear)
2. Makes scratches on wood
3. Has a bumpy surface
4. Broke when I dropped it

He thinks the glass is a solid and most of his observations could only apply to a solid. Which one of his observations could possibly apply to a solid, a liquid or a gas?

A. 1
B. 2
C. 3
D. 4

Answer 1

Answer = A (1. No color, clear)
Solids can be clear; ex: an ice cube
Liquids can be clear; ex: water
Gases can be clear; ex: Hydrogen gas

Can't be #2 b/c liquids and gases do not scratch up wood.
Can't be #3 b/c gases cannot and liquids do not have bumpy surfaces.
Can't be #4 b/c you can't drop and break gases.
