Copper is a good conductor
Answer:
Since the tape has extra electrons, it has a negative charge. When you move your finger close to the tape, electrons in your skin are repelled and move away. This makes the skin on your finger tip have a slight positive charge. Since positive and negative attract, the tape moves toward your finger.
Answer: 12L
Explanation:
To find the correct volume of the balloon, we can use the mathematical representation of Boyle’s law which states that a gas’s volume is inversely proportional to its pressure (as one increases the other decreases).
The equation for it is P1 * V1 = P2 * V2 where P1 and V1 represent the initial pressure and volume of the gas and P2 and V2 represent its changed temperature and volume.
In this case, the initial pressure of the gas inside the balloon is 3atm while its initial volume is 2.0L. Its pressure is then reduced to 0.5atm.
If we apply this information to the equation for Boyle’s law, we get
2L * 3atm = 0.5atm * V2.
Through arithmetic, we find that
6 = 0.5atm * V2
6/0.5atm = V2
12L = V2.
So, the volume of the balloon is 12L.
Hope this helps!
