What are the field lines for a positive charge?
The field lines for a positive charge are radial lines extending outward in all directions from the charge. The field lines indicate the direction of the electric field, pointing away from the positive charge. The field lines are more concentrated closer to the charge and spread out further away.
What happens when a balloon is exposed to heat?
When a balloon is exposed to heat, the air molecules inside the balloon start to move faster and spread out, causing the balloon to expand. If the heat is too intense, the balloon may burst due to the increased pressure inside.
Why does the volume of a balloon increase as the balloon is heated?
Heating a balloon causes the air molecules inside the balloon to move faster and spread out, increasing the volume of the balloon. This is because the kinetic energy of the molecules increases, pushing against the walls of the balloon and expanding it.
What happens to the volume in a balloon when heated?
When a balloon is heated, the air molecules inside the balloon gain kinetic energy and move faster, causing them to spread out and take up more space. This increase in volume leads to the balloon expanding.
What happens when an isolated conductor is statically charged?
When a conductor is statically charged, excess charge accumulates on its surface. This charge distribution creates an electric field within the conductor that repels like charges and attracts opposite charges. As a result, the charges redistribute themselves on the surface of the conductor until the electric field inside the conductor becomes zero.
What is charge density and how does it relate to the distribution of electric charge within a given volume?
Charge density refers to the amount of electric charge per unit volume. It is a measure of how concentrated the electric charge is within a given space. The charge density is directly related to the distribution of electric charge within that volume, as a higher charge density indicates a greater concentration of charge in a specific area, while a lower charge density indicates a more spread out distribution of charge.
Why do hot air balloons float in the ar?
As the air in the balloon is heated, it expands and becomes less dense, or that is, becomes lighter. This then provides lift to the balloon and the basket. The reason the air in the balloon expands, is because as it is heated, the molecules of air move faster and spread out to fill the entire volume of the balloon.
Why does a balloon stick to a wood wall but not a metal one?
It probably would... If the metal wall area were small enough and not grounded. As the charged balloon touches the conductive metal wall, the wall quickly 'absorbs' and spreads the unbalanced charge throughout it's mass. (It only conducts away the charge from the part of the balloon touching the wall...) After dissipating the unbalanced charge from the balloon, there's no 'positive' / 'negative' charge separation to cause an attractive force so the balloon doesn't stick. In other words, the balloon looses part of its charge to the wall that has a much greater ability to store and spread electrical charges. Conductors, such as the metal wall, cannot be forced to maintain localized charge imbalances (like insulators can) as the imbalances are quickly conducted away. The electroscope experiment shows that conductors (small, ungrounded) CAN maintain net electrical charges (the foil leaves spread due to their holding like charges).

Why does a balloon inflate when held in hot water?
When a balloon is held in hot water, the air inside the balloon heats up, causing the air molecules to move faster and spread out. This increases the pressure inside the balloon, pushing against the flexible walls and causing the balloon to inflate.
What causes the balloon to expand when heated?
Heating the air inside the balloon causes the air molecules to move faster and spread out, increasing the pressure inside the balloon. This increase in pressure pushes against the balloon's walls, causing it to expand and inflate.
How did the particles inside the balloon move?
The particles inside the balloon moved randomly due to the kinetic energy they possess. The temperature of the gas inside the balloon affects the speed at which the particles move. When the gas inside the balloon is heated, the particles move faster and spread out, causing the balloon to expand.
What would happen to the volume of a balloon if it were submerged in hot water?
The volume of the balloon would increase when submerged in hot water because the heat causes the air particles inside the balloon to move faster and spread out, increasing the overall volume of the balloon.
