To turn candle wax into a liquid state, heat it gently. The heat raises the wax’s temperature, causing it to melt. Use a heat source like a candle warmer or a pot of hot water.
The water in an earthen pot is cold because the porous material allows evaporation of water from the surface. This process absorbs heat, lowering the temperature of the remaining water inside the pot.
When water is sprinkled on a hot pan, it evaporates quickly. The heat causes the water to change from liquid to vapor, which disperses into the air, making it seem like it has disappeared.
Temperature affects the state of water by influencing its phase transitions. Increasing temperature can cause ice to melt or water to evaporate, while decreasing temperature can lead to freezing or condensation of water vapor.
