Robbie wants to know if a ring is made of real gold. First, he drops the ring into a cylinder with water and measures how much the water rises. Then, he places the ring on a balance and records the result. Which scenario most likely explains how Robbie is trying to find out if the ring is real gold?
- He has found the mass and weight. He will now compare them to Earth's gravity to see if it matches the weight and mass of gold.
- He is going to attach the ring to wires to measure its conductivity after being in water and divide that by its mass.
- He found that the ring did not float, so he is finding its mass to see if it is more dense than water. If it is, he knows it is gold.
- He found the volume and mass and is now going to multiply them to find the specific atomic mass.
- He has measured the volume and mass. He will now divide the mass by the volume to see if the value matches the density of gold.
