01. Solubility Table
Q1 Answer: Direct relationship. As temperature increases (10 → 50), solubility consistently increases (15.2 → 58.3).
Q2 Answer: Approximately 35.0 - 37.0 g/100mL. (Interpolation between 30°C [30.8] and 40°C [42.1]).
02. Fertilizer Bar Graph
Q3 Answer: Brand B (Highest bar reaching 30cm).
Q4 Answer: 9 cm (30 cm - 21 cm = 9 cm difference).
03. Population Line Graph
Q5 Answer: Prey. The blue dashed line reaches its minimum y-value (highest population) at time interval 4.
Q6 Answer: The Predator population is decreasing/declining. After the peak near week 4, the red line trends downward toward the baseline.
04. Enzyme Scatter Plot
Q7 Answer: pH 7. The peak of the distribution occurs at the horizontal center (pH 7).
Q8 Answer: Non-linear (Bell Curve). The data points increase and then decrease, rather than forming a straight line.
05. Atmospheric Composition
Q9 Answer: Nitrogen (78%).
Q10 Answer: 210 liters (0.21 x 1000 = 210).

01. Specific Heat Table
Q1 Answer: Lead. It has the lowest value (0.128 J/g°C), meaning it heats up with the least resistance.
Q2 Answer: Gold. Because it has a much lower specific heat (0.129) than Iron (0.450), the same amount of heat energy will cause a significantly higher temperature increase in gold.
02. Ocean Plastics Bar Graph
Q3 Answer: Packaging (represented by the tallest bar at ~6.5M tons).
Q4 Answer: 2.8 Million. The Textiles bar aligns between the 2.0 and 4.0 markers, approximately slightly below the halfway point.
03. Enzyme Temperature Curve
Q5 Answer: 25°C. The peak of the green reaction curve occurs at the horizontal point labeled 25°C.
Q6 Answer: The enzyme denatures. High heat breaks the molecular bonds holding the enzyme's shape together, preventing it from catalyzing the reaction.
04. Tree Scatter Plot
Q7 Answer: Strong Positive. The data points form a very tight, upward-sloping line.
Q8 Answer: Approximately 50-55 cm. (Following the linear trend between age 40 and 60).
05. Global Water Distribution
Q9 Answer: Saltwater (making up 97.5% of Earth's total water volume).
Q10 Answer: Only a very small percentage of Earth's water is freshwater (2.5%), and much of that is inaccessible (glaciers). This highlights the scarcity of usable water.
