evaporation is a physical change
true
false
question 8 (1 point)
burning wood is a physical change
true
false

Explanation:

• Changing the size and shape of wood is a physical change as it only alters physical appearance, not chemical composition. So the first statement is false.
• In a physical change, the makeup of matter (chemical composition) remains the same, so the second statement is false.
• Evaporation is the process of liquid water changing to gas state, so the third statement is true.
• Evaporation is a physical change as it only involves a change of state without altering the chemical identity of water, so the fourth statement is true.
• Burning wood involves a chemical reaction (combustion) that changes the chemical composition of wood, so it is a chemical change, not a physical change, and the fifth statement is false.
