Volume vs Temperature
We are using the flask that connects with a plunger and temperature pro to measure the changes of volume when temperature changed. Base on the theorem of thermal expansion state that when a object is heated, its particles begin moving more and thus usually maintain a greater average separation; therefore, volume of air increases when temperature increased.
Recorded experiment data and graph of temperature vs volume. The reason that the pressure of the air remains constant even if the volume of the air in the system changes is the air inside the system will balance with atmospheric pressure automatically if the system without any external force.
There is linear relationship between temperature and volume. Volume is directly proportional to temperature.
