Final answer:
When Volume is plotted against Temperature for an ideal gas at constant pressure, one typically obtains a linear graph according to Charles's Law. This direct relationship means that the correct answer is that a V vs T graph is linear.
Step-by-step explanation:
The relationship between Volume (V) and Temperature (T) is understood in physics to be a direct one, especially if you are looking at an ideal gas following Charles's Law which states that volume is directly proportional to temperature when pressure is held constant. When the volume of a gas increases, the temperature also increases, and vice versa, as long as the pressure and the amount of gas present remains constant. Therefore, if you plot Volume (V) against Temperature (T) with these conditions in mind, you will get a linear graph where the line will slope upwards if the constant pressure is positive.
In other scenarios, however, like in more complex systems or non-ideal gases, the relationship may not be strictly linear. But the reference information provided does not suggest any such complexities, and the standard assumption in high school level physics would typically be a linear relationship unless specific non-ideal conditions are mentioned. Hence, based on the available information, the most likely answer would be linear for a V vs T graph.
