What happens to particles in a hot air balloon?
The pressure inside the hot air balloon is affected by temperature. As the molecules heat up, they move faster and strike the inside wall of the balloon harder. This increased motion of the gas particles increases the force on an area of the balloon, producing a rise in the pressure.
How do air particles move in a balloon?
Gas pressure Since the particles in a gas are moving fast and randomly, collisions occur frequently. For example, the collisions caused by a gas trapped inside a balloon cause forces to act outwards in all directions, giving the balloon its shape.
What state of matter is inside the balloon explain your answer?
Gases
How does the particles inside the balloon move as they gain heat slower or faster?
When gas molecules are warmed, their average kinetic energy also increases. This means they move faster and have more frequent and harder collisions inside of the balloon. When cooled, the kinetic energy of the gas molecules decreases, meaning they move more slowly and have less frequent and weaker collisions.
What eventually happens if you heat up the container too much or push down too much?
Heating increases pressure They hit the walls of their container harder and more often. This increases the pressure. Sometimes the pressure gets so great that the container bursts. This is why balloons and tyres burst if you blow them up too much.
What happens to a film of bubble solution when the air inside a bottle is warmed and cooled?
Explain that heating the air inside the bottle makes the molecules move faster. These molecules push against the inside of the bubble film harder than the surrounding air pushes from the outside. This pushes the bubble film up and out, forming a bubble. Note: Cooling the gas makes the molecules move more slowly.
What do you predict will happen when you place the balloon over the heating pad and let it go?
Air expands when it is heated; it spreads out and either fills a larger space or raises the pressure in a closed space. The air molecules moved faster and faster as the temperature rose and they could spread out and fill a larger space as a result. The expanding balloon showed that this was happening.
How would you compare the movement of particles in hot water and cold water?
Point out to students that molecules of hot water are moving faster and are slightly further apart. The molecules of cold water are moving slower and are a little closer together.
When a gas is cooled the motion of the particles slow down?
If the particles close enough energy their attraction for each other can overcome their motion and cause them to associate with one another to become liquid.
What happens to the particles in matter when temperature is increased?
With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion. In a solid, the particles pack together as tightly as possible in a neat and ordered arrangement.
Is the change of state from a liquid to a gas?
Matter changes between the liquid and gas states through vaporization and condensation. The change from a liquid to a gas is known as vaporization (vay puh ruh ZAY shun). You can see in Figure 11 that the temperature of the substance does not change during vaporization. However, the substance absorbs thermal energy.
Why do particles of solids Cannot move around?
Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. Their vibration is related to their kinetic energy. In the solid the particles vibrate in place.
How do particles move in hot water?
Molecules in a liquid have enough energy to move around and pass each other. Warm water has more energy than cold water, which means that molecules in warm water move faster than molecules in cold water. The food coloring you add to the water is pushed around by the water molecules.
Why do particles move faster heat?
All three states of matter (solid, liquid and gas) expand when heated. The atoms themselves do not expand, but the volume they take up does. Heat causes the molecules to move faster, (heat energy is converted to kinetic energy ) which means that the volume of a gas increases more than the volume of a solid or liquid.
Does cold water move slower?
The molecules of cold water move slower than the molecules of hot water. The molecules of cold water move at the same speed as the molecules of hot water. It is not possible to say anything about how the molecules differ without more information.
Why the force of attraction between solid particles is stronger?
Answer: Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart and move freely of each other.
What are the strongest to weakest intermolecular forces?
In order from strongest to weakest, the intermolecular forces given in the answer choices are: ion-dipole, hydrogen bonding, dipole-dipole, and Van der Waals forces.
What causes the attractive forces between particles in matter?
The particles that make up some matter are close together and vibrate back and forth. If the motion of particles slows the particles move closer together. This is because the attraction between them pulls them toward each other. Strong attractive forces hold particles close together.
