Question

jenna was outside blowing up a balloon for her little sisters birthday party. she tied it closed, but then dropped it by accident. when the balloon touched the grass a few seconds later, it popped. which graph could show the amount of air in the balloon over time?

Explanation:

Step1: Analyze balloon filling phase

As Jenna blows up the balloon, the volume of air increases over time, so the graph rises from 0.

Step2: Analyze tied balloon phase

When the balloon is tied closed, the volume of air stays constant for a period (the time until it's dropped and pops), so the graph is a horizontal line.

Step3: Analyze popping phase

When the balloon pops, the volume of air drops to 0 instantly, so the graph has a sharp vertical drop to the x-axis.

Answer:

The right graph (horizontal plateau then sharp drop)
