a substance is tested in a lab. it is found to maintain a unique shape and is a good conductor of electricity. if it is made up of electrons, protons, and neutrons, what state of matter is this substance most likely to be?\n gas\n liquid\n plasma\n solid
Answer
Answer:
D. solid
Explanation:
Step1: Analyze gas properties
Gases have no definite shape and expand to fill their container. So it's not gas.
Step2: Analyze liquid properties
Liquids have a definite volume but take the shape of their container. So it's not liquid.
Step3: Analyze plasma properties
Plasma is a high - energy state with free - flowing charged particles and is not a good conductor in the same sense as solids and has no definite shape like a solid. So it's not plasma.
Step4: Analyze solid properties
Solids maintain a unique shape and some solids (metals) are good conductors of electricity. Since the substance maintains a unique shape and is a good conductor, it is most likely a solid.
