Question

What Celsius temperature, rounded to the tenth of a degree, is required to change the volume of a gas sample?

a) 0.1°C
b) 1.0°C
c) 10.0°C
d) 100.0°C

Answer 1

The question involves the application of Charles's Law in physics, which relates the temperature of a gas to its volume at constant pressure. Even a small change in temperature, such as 0.1°C, will influence the volume of a gas, demonstrating that temperature directly affects gas volume.

Step-by-step explanation:

The question pertains to the relationship between the temperature and volume of a gas at constant pressure, a concept governed by the Charles's Law from thermodynamics in physics. This law states that, at constant pressure, the volume of a gas is directly proportional to its temperature measured in Kelvin. Applying this to the examples provided, such as the sample of gas initially at 14.0 °C with a volume of 997 mL that is then heated to 100.0 °C, allows us to calculate the final volume of the gas. Similarly, we can find the final temperature when given the initial and final volumes under constant pressure conditions, such as the sample of carbon monoxide given or the gas thermometer measuring boiling liquid ammonia. In essence, any change in temperature, even if it is only by 0.1°C, 1.0°C, 10.0°C, or 100.0°C, will lead to a change in the volume of the gas assuming pressure and the number of moles of gas remain constant.
