Scienceworld Substance Cooler

This skill initiates the cooling of a substance by moving it into a cooling appliance like a freezer. Use when a task requires lowering the temperature of a specific material to observe phase changes. The skill takes the substance (often in a container) and the target appliance as inputs, using the 'move OBJ to OBJ' action. It outputs confirmation of the new location.

Skill: Substance Cooler

Purpose

Use this skill to begin the process of cooling a substance to potentially observe a phase change (e.g., freezing). The core action is to relocate the substance into a cooling appliance.

When to Use

The task explicitly requires cooling a substance (e.g., "measure the melting point of mercury").
You have identified both the target substance (often inside a container like a cup or jar) and a suitable cooling appliance (e.g., freezer, ultra low temperature freezer).
The immediate goal is to lower the substance's temperature.

Core Instruction

Locate Items: Ensure you are in the room containing the target substance and the cooling appliance. Use look around if necessary.
Execute Move: Perform the action move <SUBSTANCE_CONTAINER> to <APPLIANCE>.
- <SUBSTANCE_CONTAINER>: The object holding the substance (e.g., "glass cup (containing a substance called mercury)").
- <APPLIANCE>: The cooling device (e.g., "freezer").
Verify: Use look at <APPLIANCE> to confirm the substance is now inside the appliance. Report this confirmation.

Important Notes

Prerequisite: The appliance door must be open. The trajectory shows all containers are already open, so this should not require a separate open action.
This is an Initialization Skill: This skill only starts the cooling process. Subsequent skills or actions (like use thermometer on <SUBSTANCE>) are required to monitor temperature changes and observe the phase transition.
Inputs: The skill requires the names of the substance container and the target appliance as identified in the environment observations.
Output: A confirmation observation stating the substance is now inside the appliance.

Example from Trajectory

Trigger: Task requires measuring the melting point of mercury. Action: move glass cup (containing a substance called mercury) to freezer Verification: look at freezer yields "In the freezer is: a glass cup (containing a substance called mercury)." Output: "The mercury in its glass cup has been placed into the freezer to begin cooling."
