Water boils at 100°C and turns into steam. Which similarities or differences are there between water at 100°C and steam at 100°C? (1 point)
Responses
The particles will have more space between them and will be moving at higher speeds as steam.
The particles will have more space between them as a liquid, but they will be moving faster as steam.
The particles will have more space between them as a liquid, but they will be moving at the same speed in both states.
The particles will have more space between them as steam, but they will be moving at the same speed in both states.
The correct response is:
The particles will have more space between them and will be moving at higher speeds as steam.
To understand the similarities and differences between water at 100°C and steam at 100°C, we need to understand the concept of phase changes.
When water is heated to 100°C, it undergoes a phase change from a liquid to a gas, resulting in the formation of steam. At this point, both the liquid water and the steam exist at the same temperature of 100°C.
In the liquid state, the water molecules are relatively close to each other and have some freedom to move around, but they are still relatively densely packed. However, as the water reaches its boiling point and turns into steam, the intermolecular forces holding the water molecules together are overcome, allowing the particles to break free and move further apart.
As a result, in the gaseous state (steam), the particles have more space between them compared to when they were in the liquid state. This increased space allows the water molecules to move more freely and independently, leading to higher average speeds. Therefore, as steam, the particles will have more space between them and will be moving at higher speeds compared to water at the same temperature.
In summary, the main difference between water at 100°C and steam at 100°C is the arrangement of particles and their movement. Steam has more space between particles and higher average speeds compared to water in its liquid state.
