Final answer:
The change in pressure of the gas is 275.0 torr.
Step-by-step explanation:
The change in pressure of a gas can be calculated using the ideal gas law, which states that pressure is directly proportional to temperature, assuming volume is constant. In this case, the temperature increased from 100.0°C to 175°C, and the pressure changed from 650.0 torr to 925 torr. To find the change in pressure, subtract the initial pressure from the final pressure: 925 torr - 650.0 torr = 275.0 torr. Therefore, the change in pressure is 275.0 torr.
