Water to Steam: Understanding the Sequence of Events
The question describes a process involving water changing into steam and then back into water. Let's break down the steps mentioned in the passage:
- Step 1: Water is heated.
- Step 2: The heated water boils.
- Step 3: Steam is produced from boiling water.
- Step 4: The steam cools down.
- Step 5: Cooled steam condenses (turns back into water).
Analyzing the Statements for Accuracy
We need to check which of the given statements accurately reflect this sequence.
Statement (a): Steam is produced before the water boils.
According to the passage, "Then, it boils. Next, steam is produced." This clearly indicates that boiling happens before steam is produced. Therefore, statement (a) is incorrect.
Statement (b): Water is heated before it boils.
The passage states, "First, water is heated. Then, it boils." This sequence matches the statement perfectly. Heating the water is the necessary first step that leads to boiling. Therefore, statement (b) is correct.
Statement (c): Steam cools and condenses after it is produced.
The passage says, "Next, steam is produced. Finally, the steam cools and condenses." This shows that cooling and condensation happen *after* the steam has already been produced. Therefore, statement (c) is correct.
Statement (d): The process starts with the cooling and condensing of steam.
The passage explicitly begins with "First, water is heated." Cooling and condensing of steam is the final step described, not the starting point. Therefore, statement (d) is incorrect.
Determining the Correct Option
Based on our analysis:
- Statement (b) is correct.
- Statement (c) is correct.
The option that includes both correct statements (b) and (c) is the accurate description of the sequence of events.
