Question

1.)Which of these statements correctly compares probeware (such as an electronic temperature probe) to traditional analog tools (such as a liquid-based thermometer)
A) measurements by traditional analog tools are good to a larger number of significant figures.
B) measurements by traditional analog tools are less prone to experimental error
C) probeware is typically very difficult to transport
D) probeware is useful for obtaining many meaurements in rapid succession.

2.) Which tools should be used to record the most complete data about a gas?

A) A gas-collecting bottle and an electronic balance
B) A graduated cylinder and a thermometer
C) A syringe and a manometer

Answer 1

1. The correct answer is option D, that is, probeware is useful for obtaining many measurements in rapid succession.  

Probewares are usually used to gather precise information, with less amount of error in real time, and evaluate the outcome with the help of powerful tools. The probewares are easy to handle and at the same time are cost-effective. Thus, the correct statement is that probeware is useful for attaining many measurements in quick succession.  

Answer 2

1. D)
2. I think the correct answer from the choices listed above is option C. The tools that should be used to record the most complete data about a gas are a manometer and a thermometer. Pressure and temperature are important measurements for a gas since from these data we can calculate any other properties of the gas.
