No, because matter is microscopic, but it is there. We can find matter in gaseous, liquid and solid states. If it can be produced, the solid bicarbonate and the liquid vinegar were transformed into gas. Density is the ratio between mass and volume. It is important because, as it has a higher density than air, the gas sinks.
We have observed a compass pointing to the North. Question 1. Can we change its direction? 2.Can we make the same without using a magnet? Hypothesis No, because a compass always points to the North because the Earth has magnetism. Experiment Procedure 1. Wire 1: Place one extreme of a wire to the battery. 2. Connect the other extreme to the other part of the battery. 3. Place the wire on the compass. 4. Observe Results The compass doesn’t point to North. Conclusion We have created a magnetic field. So the magnet of the compass doesn’t know where to point because there are two magnetic fields next to it. The compass becomes “crazy”.
