about three-five minutes. We had to coil the wire in a circle and put it in the glass. I want to know if the weight stays the same, goes down, or goes up after the three-five minutes are up. Also, what happens during that time (observations)?! I don‘t know if I‘m being specific enough or what but I‘ll give the directions I was given.1. Obtain a 10 cm piece of copper wire.2. Find the mass of the wire and record it here (0.1g.)3. Set up the apparatus for heating the wire in a crucible.4. Coil the wire in the crucible and heat with the cover off for 3-5 minutes. BE CAREFUL - IT WILL GET VERY HOT.5. Allow the wire to cool for at least 5 minutes.6. Find the mass of the wire and record it here (___g.)NO, I am not asking for answers.but my group didn‘t get to finish this little experiment. We were actually rushing. I want to do good on this sheet, so please help me out. I‘d appreciate it a lot.
The mass should go up a tad because the heated copper should have collected some oxygen atoms. How much does it go up? - no idea.
