Use the kinetic theory to explain why bubble wrap pops when it is squeezed. When the bubble is squeezed, the gas is forced into a smaller volume. If the same amount of gas is in less space, there are more particles per unit volume, causing more collisions with the walls of the container.

What happens when gas particles collide with the walls of the container?
The pressure of a gas results from collisions between the gas particles and the walls of the container.
Why does the pressure inside a container of gas increase if more gas is added to the container?
The pressure inside a container of gas increases when more gas is added to the container because the volume of the container doesn’t change, and the added gas adds more molecules to push against the sides of the container. It is the movement of the gas molecules pushing against the container that causes pressure.
What conditions result in more collisions of molecules with the walls of the container and with one another?
Volume versus Temperature: Raising the temperature of a gas increases the average kinetic energy and therefore the rms speed (and the average speed) of the gas molecules. Hence as the temperature increases, the molecules collide with the walls of their containers more frequently and with greater force.
What happens to the pressure and volume respectively inside each bubblewrap when you squeeze it?
According to Boyle’s law, if the temperature of a gas is held constant, then decreasing the volume of the gas increases its pressure—and vice versa. That’s what happens when you squeeze the bubbles of bubble wrap. You decrease the bubbles’ volume, so the air pressure inside the bubbles increases until they pop.
At what temperature does an ideal gas exert no pressure?
0°K = -273°C is known as “absolute zero”. If one could lower the temperature to absolute zero, the pressure of the ideal gas would be zero – the gas would exert no force on the walls of its container.
What happens to a gas at 0 Kelvin?
According to the physical meaning of temperature, the temperature of a gas is determined by the chaotic movement of its particles – the colder the gas, the slower the particles. At zero kelvin (minus 273 degrees Celsius) the particles stop moving and all disorder disappears.
Does pressure affect speed of gas particle?
The speed at which the individual particles of the gas move, however,isn’t dependent on the pressure– you could have a diffuse gas of slow or fast moving particles. The speed of the particles is dependent on the temperature. In fact, temperature IS the amount of motion that particles undergo.
Why does volume decrease when pressure increases?
The Relationship between Pressure and Volume: Boyle’s Law. As the pressure on a gas increases, the volume of the gas decreases because the gas particles are forced closer together. Conversely, as the pressure on a gas decreases, the gas volume increases because the gas particles can now move farther apart.
Why does temperature increase when pressure increases?
if the amount of collisions increases with pressure increase, this means that the amount of EFFECTIVE collisions also increase, and also the rate at which the molecules move is also increased. This is the cause of temperature, an increase in speed of vibration. This is why temperature increases.
Does pressure affect temperature?
For example, if air pressure increases, the temperature must increase. If air pressure decreases, the temperature decreases. It also explains why air gets colder at higher altitudes, where pressure is lower.
Does kinetic energy depend on pressure?
Kinetic energy is directly proportional to the pressure.
Why can gas fill any space?
Gases are in rapid motion, and they undergo elastic collisions with each other and the walls of the container; that is, momentum and energy is transfered not lost during collisions. Gases expand spontaneously to fill any container (rapid motion).
Are real gas collisions elastic?
All collisions between gas molecules are perfectly elastic; all kinetic energy is conserved. When cars collide, energy is lost to bending bumpers and metal. Molecules do not act like this. Instead they act like billiard balls.
Why bubble wrap pops when it is squeezed Brainly?
Explanation: According to Boyle’s law, if the temperature of a gas is held constant, then decreasing the volume of the gas increases its pressure—and vice versa. That’s what happens when you squeeze the bubbles of bubble wrap.
What happens to the volume as the temperature increases?
The volume when the temperature is increased, Volume increases.
What will be changed when you squeeze a balloon?
By squeezing the balloon, you reduce the space the gas particles can occupy. As the particles are pushed a bit closer together, they collide with more, so the pressure from the moving gas particles increases. Boyle’s Law explains the relationship between volume and pressure.
Is co2 an ideal gas?
Many gases such as nitrogen, oxygen, hydrogen, noble gases, some heavier gases like carbon dioxide and mixtures such as air, can be treated as ideal gases within reasonable tolerances over a considerable parameter range around standard temperature and pressure.
Do heavier gases exert more pressure?
Although the collisions are less frequent, the heavier gas has more momentum. Because of this, it strikes the sides of its container with more force, albeit less often. Supposedly, this makes up for the lower collision frequency in the heavier gas. This is why both gases have the same pressure.
Why is there no pressure at absolute zero?
Absolute zero can be defined as the temperature at which matter does not move. At absolute zero, even subatomic vibrations are put to a grinding halt. Because the pressure in this experiment is caused by the movement of a gas, the pressure would cease to exist when the gas stops moving (a.k.a. absolute zero).
Which temperature can never exist?
Absolute zero, technically known as zero kelvins, equals −273.15 degrees Celsius, or -459.67 Fahrenheit, and marks the spot on the thermometer where a system reaches its lowest possible energy, or thermal motion. There’s a catch, though: absolute zero is impossible to reach.
Does time stop at absolute zero?
But even if you take the conventional view of the flow of time, motion does not stop at absolute zero. This is because quantum systems exhibit zero point energy, so their energy remains non-zero even when the temperature is absolute zero.
What is the coldest temperature in the universe?
Physicists acknowledge they can never reach the coldest conceivable temperature, known as absolute zero and long ago calculated to be minus 459.67°F.
What is K in Boyle’s law?
Boyle’s law—named for Robert Boyle—states that, at constant temperature, the pressure P of a gas varies inversely with its volume V, or PV = k, where k is a constant.
What is Boyle’s law states?
This empirical relation, formulated by the physicist Robert Boyle in 1662, states that the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature; i.e., in equation form, pv = k, a constant.
