Question

question 1
identify the following as either matter or not matter (energy):
a. glass not matter (energy) select
b. air matter not matter (energy)
c. heat not matter (energy)

Explanation:

Step1: Recall matter definition

Matter has mass/volume.

Step2: Analyze air

Air has mass (gases) & volume. So air is matter.

Step3: Analyze glass (correction)

Glass is solid matter (mass/volume). Previous selection was wrong, but for part b (air), it's matter.

Step4: Analyze heat

Heat is energy (no mass/volume), so not matter.

Answer:

a. glass: matter (correction from original wrong), b. air: matter, c. heat: not matter (energy)

For part b (air) selection: matter
