Step-by-step solution for: SOLUTION: Mythbusters who gets wetter - Studypool
It looks like you've uploaded an image that includes a table and a graph titled "Time vs Water Absorbed", but the details are blurry or missing. However, based on what is visible:
- There's a table with columns:
- Trial
- Wind
- Time (s)
- Initial Mass of Salt (g)
- Final Mass of Salt (g)
- Water Absorbed (g)
- A graph plotting "Time Spent in the Sun (s)" on the x-axis and "Water Absorbed (g)" on the y-axis.
The graph appears to have two data sets:
- One labeled: “Amount of water absorbed while heating”
- Another: “Amount of water absorbed while cooling”
But due to the low resolution, specific values are not readable.
---
This seems to be a science experiment involving:
- A salt (likely a hygroscopic substance like calcium chloride or sodium sulfate)
- Measuring how much water it absorbs over time under different conditions (e.g., heating vs. cooling)
- Possibly testing the effect of wind or temperature on absorption rate
---
Let’s suppose the goal is to analyze the data and answer questions such as:
1. How does time affect water absorption?
2. Does wind influence the rate of absorption?
3. What is the relationship between temperature (heating/cooling) and water absorption?
#### Step 1: Understand the Data
From the table:
- The initial mass of the salt is measured.
- After exposure (time), the final mass is recorded.
- The water absorbed = Final Mass – Initial Mass
Example (hypothetical):
| Trial | Wind | Time (s) | Initial Mass (g) | Final Mass (g) | Water Absorbed (g) |
|-------|------|----------|------------------|----------------|---------------------|
| 1 | No | 5 | 10.0 | 14.5 | 4.5 |
| 2 | Yes | 5 | 10.0 | 16.0 | 6.0 |
→ Wind increases absorption rate.
#### Step 2: Analyze the Graph
If the graph shows:
- Two lines: one for heating, one for cooling
- And both show increasing water absorbed with time
Then:
- Heating may increase evaporation or speed up diffusion → more water absorbed quickly?
- But if the salt is absorbing moisture from air, higher temperature might reduce humidity → less absorption?
Wait — contradiction possible.
Actually, hygroscopic salts absorb water vapor from the air. So:
- In high humidity, they absorb more.
- Temperature affects humidity: warm air holds more moisture, but also may dry out faster.
So:
- If the salt is heated, it might release water (if already hydrated).
- If it's cooled, condensation might occur → more absorption.
Thus, the "amount absorbed while cooling" likely shows higher absorption than when heating.
#### Step 3: Interpret the Graph
Suppose:
- The cooling line rises steeply.
- The heating line levels off or decreases.
That would suggest:
> Cooling enhances water absorption by the salt.
#### Step 4: Conclusion
Based on typical behavior:
- Cooling favors water absorption.
- Wind increases evaporation/convection → may increase absorption rate.
- Time increases total absorption, up to saturation.
---
> The salt absorbs more water during cooling than during heating. This is because cooler air can hold less moisture, leading to higher relative humidity and increased absorption. Wind increases the rate of water absorption by enhancing air circulation around the salt. Over time, the amount of water absorbed increases until the salt reaches its maximum capacity.
---
⚠️ Note: Without clearer data, this is an inference based on typical experimental setups.

Please re-upload a clearer version of the image or provide:
- The actual numbers from the table
- The exact question being asked
Then I can give you a precise solution with calculations and reasoning.
