Question

Instead of measuring the volume ofH2 produced, the pressure change wasmeasured. This requires knowing what theinitial pressure is. Which of the followingwould have the least influence on the initialpressure inside the flask?A. altitudeB. weather conditionsC. time of day

Answer 1

As we know by the gases law, both altitude and weather conditions can influence the pressure of a gas.

So the time of the day would have the least influence on the initial pressure inside the flask.

Answer: Time of day; alternative "C".
