Final answer:
The volume of the air at 50°C, assuming constant pressure, is 109.26 ml.
Step-by-step explanation:
The volume of a gas increases as its temperature increases, assuming the pressure remains constant. This relationship is described by Charles's law. According to Charles's law, the volume of a gas is directly proportional to its temperature in Kelvin. To solve this problem, we can use the formula:
V1 / T1 = V2 / T2
Given:
V1 = 100 ml
T1 = 20°C = 293 K
T2 = 50°C = 323 K
Using the formula, we can solve for V2:
V2 = (V1 * T2) / T1 = (100 ml * 323 K) / 293 K = 109.26 ml
Therefore, the volume of the air at 50°C will be approximately 109.26 ml.
