How Does Temperature Affect Gas Volume in Syringes?

What happens to the volume of gas in syringes when they are exposed to heat?

Would the volume of both syringes increase by the same amount?

Answer:

No, the volume of both syringes would not increase by the same amount.

According to Charles's Law, the volume of a gas is directly affected by temperature changes. When a gas is heated, its volume increases. In the given scenario where a 10 mL syringe is filled with 2 mL of carbon dioxide gas and another syringe with 5 mL of air, and both are placed in the same hot water bath, the volume increase of the gases will not be the same.

Carbon dioxide gas (CO2) has a lower initial volume of 2 mL compared to the air in the second syringe with an initial volume of 5 mL. Therefore, when both syringes are subjected to the same temperature increase, the air in the second syringe will undergo a larger volume increase compared to the carbon dioxide in the first syringe. This is because the initial volumes of the gases play a crucial role in determining the extent of volume expansion when exposed to heat.

It is important to consider the initial volume of the gas and the type of gas when analyzing how temperature affects gas volume in syringes. Understanding Charles's Law helps in predicting the behavior of gases when subjected to temperature changes.
