網頁PARTICLE MODEL 33 Figure 2.8 You can sometimes see condensation when you breathe out on a cold morning. The water gas in your breath becomes a fine liquid when it hits the cold air, making what is commonly called ‘dragon breath’. Check your learning 2.1 網頁Even more energy is required to vaporize water; it would take 2256 kJ to change 1 kg of liquid water at the normal boiling point (100ºC at atmospheric pressure) to steam (water vapor). This example shows that the energy for a phase change is enormous compared to energy associated with temperature changes without a phase change.

Water to steam: How does the pressure make a difference?

網頁2016年3月26日 · However, the graph levels out during phase changes, because on a molecular level, making a substance change state requires energy. After all the material has changed state, the temperature can rise again. Phase changes of water. Imagine that someone has taken a bag of ice and thoughtlessly put it on the stove. 網頁2024年11月22日 · As more water vapor condenses, cloud volume increases, and the chance of precipitation increases. Instability occurs when clouds increase in height and are surrounded by warmer air. These conditions can trigger thunderstorms. Liquid or frozen water falls to the surface as precipitation. cecil county public schools academic calendar

Thermal expansion is large for gases, and relatively small, but not negligible, for liquids and solids. Linear thermal expansion is ΔL = αLΔT, where ΔL is the change in length L, ΔT is the change in temperature ... cecil county public schools bid board
