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?\no gas\no liquid\no plasma\no solid
Answer
Brief Explanations:
Solids maintain a unique shape due to closely - packed particles. Good electrical conductivity is a characteristic of many solids (like metals) which have free - moving electrons. Gases and liquids do not maintain a fixed shape, and plasma is a highly ionized state different from the description given.
Answer:
D. solid
