1. A micrometer screw gauge. Send me the next one 📸 2. The water level in the test tube will rise. Water exhibits anomalous expansion; it expands when cooled from 4^ C to 0^ C, increasing its volume. Send me the next one 📸 3. Observation: The water level in tube X will rise, and the water level in tube Y will fall. Explanation: Bulb Q, being black, is a better absorber of heat radiation than bulb P, which is white. When the heater is turned on, the air inside bulb Q heats up and expands more than the air in bulb P. This increased expansion in Q pushes the water level down in tube Y and consequently up in tube X. Send me the next one 📸 4. The candle becomes more stable. As the candle burns, its mass decreases and its center of gravity lowers. A lower center of gravity increases the stability of an object. Send me the next one 📸 5. Earthen jars are porous, allowing water to seep through to the outer surface. This water then evaporates, taking latent heat from the remaining water inside the jar, which causes a cooling effect. Metallic jars are non-porous, so this evaporative cooling does not occur. Send me the next one 📸
