Question

1. at what temperature did the hot and cold beakers reach thermal equilibrium in each of the experiments?

draggable item | category:
experiment 3 → 13.2 °c;
experiment 1 → 24 °c;
experiment 4 → 36 °c;
experiment 2 → 48 °c.

fig 1: data from experiment 1 - room temp. water (chart: temperature of water in large beaker (°c, blue) and temperature of ice in small beaker (°c, red) vs time (mins), lines converging).

fig 2: data from experiment 2 - 40 °c water (chart: temperature of water in large beaker (°c, blue) and temperature of ice in small beaker (°c, red) vs time (mins), lines converging).

Explanation:

To determine the thermal equilibrium temperature for each experiment, we analyze the graphs (Fig 1 for Experiment 1 and Fig 2 for Experiment 2, and likely similar for Experiments 3 and 4). Thermal equilibrium is when the temperatures of the hot and cold beakers stabilize (the point where the two temperature curves meet). From typical experimental setups and the given draggable items:

• Experiment 1 (Room Temp. water, Fig 1) shows equilibrium around \(24^\circ\text{C}\) (matching the curve intersection).
• Experiment 2 (40 \(^\circ\)C Water, Fig 2) has a higher initial hot water temp, so equilibrium around \(36^\circ\text{C}\) (consistent with curve trends).
• Experiment 3 (likely a different setup, e.g., lower hot water temp) would reach \(13.2^\circ\text{C}\).
• Experiment 2 might have a typo, but Experiment 2 (if initial hot water is higher, maybe 60 \(^\circ\)C as per Fig 2's y - axis) could reach \(48^\circ\text{C}\) (but re - checking: Fig 2's hot water starts at 60 \(^\circ\)C, so equilibrium around 36? Wait, no—maybe the labels: Let's match the experiments to the temps. Assuming:
• Experiment 1 (Room temp hot beaker) → \(24^\circ\text{C}\) (from Fig 1, the two lines meet at ~24).
• Experiment 2 (40 \(^\circ\)C hot beaker) → \(36^\circ\text{C}\) (Fig 2, lines meet at ~36).
• Experiment 3 → \(13.2^\circ\text{C}\) (lower equilibrium).
• Experiment 2 (maybe a different experiment, e.g., higher initial hot temp) → \(48^\circ\text{C}\) (but likely the intended matches are:

Experiment 1 → \(24^\circ\text{C}\)
Experiment 2 → \(36^\circ\text{C}\)
Experiment 3 → \(13.2^\circ\text{C}\)
Experiment 4 → \(48^\circ\text{C}\) (or adjust based on graph trends, but the draggable items are given as such).

Answer:

Experiment 1 → \(24^\circ\text{C}\)
Experiment 2 → \(36^\circ\text{C}\)
Experiment 3 → \(13.2^\circ\text{C}\)
Experiment 4 → \(48^\circ\text{C}\)

(Note: The exact matches depend on the experimental data in the graphs, but based on the provided draggable items and typical thermal equilibrium behavior, these are the likely pairings.)
