🔥Heating water causes it to change from liquid to gas, known as a phase change.
💦The gas fills the space inside and creates pressure.
🧪Turning off the gas and closing the lid creates a vacuum, causing the gas to collapse back to liquid.
🌡️The temperature change during phase changes is due to the absorption or release of heat.
🗜️The collapse of the gas shows the relationship between volume and pressure.
What is a phase change?
—A phase change is the transition of a substance from one state to another, such as from liquid to gas.
Why does the gas collapse back to liquid?
—The gas collapses back to liquid because of the decrease in volume when it changes phase.
What causes the temperature change during phase changes?
—The temperature change during phase changes is caused by the absorption or release of heat.
What does this experiment demonstrate?
—This experiment demonstrates the relationship between volume and pressure in a confined space.
Why is this experiment important?
—This experiment helps us understand the science of phase changes and their practical applications in various fields.
