The Effect of Temperature on Gas Volume Experiment
Which experiment would BEST investigate the effect temperature has on the volume of a gas?
A. Measure the pressure of the air in a bicycle tire on a cold day.
B. Stretch a balloon over the top of a beaker filled with baking soda and vinegar, then observe how the balloon changes volume as the reaction occurs.
C. Measure the volume of a balloon filled with room temperature air; place the balloon in a freezer for an hour and measure its volume again.
D. Inflate one balloon to a large volume and another balloon to a small volume. Measure the temperature of the air released from both balloons.
Answer: C
Explanation:
The best experiment to investigate the effect temperature has on the volume of a gas is option C. By measuring the volume of a balloon filled with room temperature air, placing the balloon in a freezer for an hour, and then measuring its volume again, we can observe how temperature influences the volume of the gas inside the balloon.
When the balloon is exposed to lower temperatures in the freezer, the gas molecules inside the balloon will lose kinetic energy and move more slowly, causing the volume of the gas to decrease. This change in volume demonstrates the relationship between temperature and gas volume, as described by Charles's Law in thermodynamics.
By conducting this experiment, we can determine how changes in temperature affect the volume of a gas and gain a better understanding of the principles of gas behavior under various thermal conditions. This experimental approach allows for a direct observation of the effects of temperature on gas volume and provides valuable insights into the properties of gases.
