What is the major different between the particles in a liquid and a gas of the same substance at the same temperature?
a
The particles in the gas are moving faster than the particles in the liquid
b
The particles in a liquid are still connected, but the particles in a gas have separated from each other and now fly around to fill the container
c
The particles in the liquid have higher masses than the particles in the gas
d
The particles the gas are separated, so they absorb less heat than normal, which is why gases are typically cooler than liquids
b
The particles in a liquid are still connected, but the particles in a gas have separated from each other and now fly around to fill the container
The correct answer is b.
The major difference between the particles in a liquid and a gas of the same substance at the same temperature is that the particles in a liquid are still connected, while the particles in a gas have separated from each other and now fly around to fill their container.
The correct answer is b. The major difference between the particles in a liquid and a gas of the same substance at the same temperature is that the particles in a liquid are still connected, whereas the particles in a gas have separated from each other and now fly around to fill the container.
To understand why this is the case, we need to consider the nature of the particles in a substance and how they behave under different conditions. In both liquids and gases, the particles are in constant motion. However, the strength of the forces between the particles determines whether they are more tightly packed together in a liquid or more spread out in a gas.
In a liquid, the particles are close enough to each other that they remain connected and can attract or repel each other. This is why liquids have a definite volume and take the shape of the container. The forces between the particles are strong enough to keep them relatively close together, but not strong enough to restrict their movement completely. As a result, the particles in a liquid can move around and slide past each other, allowing the liquid to flow.
On the other hand, in a gas, the particles have more kinetic energy and they move at higher speeds. The energy of the particles overcomes the attractive forces between them, causing the particles to separate and spread out. This is why gases have neither a definite volume nor a definite shape. The particles in a gas move independently and randomly, colliding with each other and bouncing off the walls of the container. They fill the entire available space because there are no strong forces to keep them closely packed together.
To summarize, the major difference between the particles in a liquid and a gas of the same substance at the same temperature is that the particles in a liquid are still connected, while the particles in a gas have separated from each other and now fly around to fill the container.
