Latent heat is all about energy hidden in phase changes, not just temperature spikes. Represent it visually with combos like 💧🔥🌞 or 🌊☀️🔥 when discussing evaporation or condensation. Use 🌡️🌤️ when emphasizing weather-related heat transfers, or 🌞🔥🌬️ to convey heat interacting with air currents. These emojis fit well in science chats or educational posts breaking down thermodynamics without the heavy jargon.
