Consider a fixed amount of an ideal gas undergoing an isobaric process ("iso" is the greek word for equal and used as a prefix means that the word following will remain the same, so here "isobaric" mean "constant pressure"). Under these conditions doubling the temperature T of the gas will
Note: An ideal gas under these conditions is said to follow Gay-Lussac's Law (sometimes also called Charles' Law).

Double the volume.

Halve the volume.

Not change the volume.

More information is needed to answer this question.

In an isobaric (constant-pressure) process, Gay-Lussac's Law (or Charles' Law) tells us that the volume of an ideal gas is directly proportional to its temperature \( T \) when the pressure \( P \) is kept constant. Mathematically, this relationship is given by:

\[
\frac{V_1}{T_1} = \frac{V_2}{T_2}
\]

where \( V \) is the volume and \( T \) is the absolute temperature in Kelvin. 

If we double the temperature \( T \) (i.e., \( T_2 = 2 T_1 \)), then the volume \( V \) must also double to maintain the equality, given the pressure remains constant.

### Answer:
Doubling the temperature \( T \) of the gas will **double the volume**.

Would you like more details on the derivation or how this law applies in different scenarios?

1. How does an isobaric process differ from an isothermal process?
2. What happens to an ideal gas if the pressure is doubled but temperature remains constant?
3. How would the behavior change in a non-ideal gas?
4. Can the ideal gas law predict behavior at extremely high or low temperatures?
5. How does Gay-Lussac's Law relate to real-life applications, like in engines?

**Tip:** Remember to use absolute temperature (Kelvin) when applying the ideal gas laws for accurate results.
