Question

Omar observes that many buildings in his city were built using limestone. He has read that acid rain can damage limestone. He also knows that limestone reacts with acids and that chemical reactions are affected by temperature. With this in mind, he conducts an investigation to see how the amount of damage to the limestone is affected by the amount of acid on the stone.

Which statement describes the correct plan for his procedure?Rhonda watched a video taken by a camera that was lifted into the upper atmosphere by a weather balloon. She saw the balloon pop when it reached a certain height. Afterward, Rhonda wondered what effect the air pressure at high altitudes has on the volume of gas in balloons.


What scientific practice is Rhonda performing

Answer 1

Answer:he conducts the investigation to see the effect acidic water has on limestone

Step-by-step explanation:

Answer 2

Rhonda is engaging in scientific practice by forming a hypothesis about the effect of air pressure on the volume of gas in balloons after observing a balloon pop at high altitudes.

Step-by-step explanation:

The question posed by Rhonda after watching the video is a display of engaging in a scientific practice, which is forming a hypothesis. Rhonda is hypothesizing that the balloon popped due to a decrease in air pressure as it ascended to high altitudes,

subsequently leading to an increase in the volume of the gas inside the balloon until it could no longer be contained. This is based on the principles of gas laws,

which relate the volume, temperature, and pressure of a gas. Rhonda's line of questioning demonstrates an understanding of the potential relationship between these variables, which is a cornerstone of scientific inquiry.
