HELP!!! An experiment was conducted to determine if the intermolecular forces in two liquids affects their boiling points. Each
liquid was sprayed on a paper towel. Each
paper towel was wiped across a glass table to moisten the surface. The table shows a partial record of the experiment.
Experimental Record
Liquid Intermolecular Forces ?
А
relatively strong
B
relatively weak
What information should be recorded in the last column of the table?
Time taken by the liquids to start boiling
Time taken by the glass surface to dry
Volume of liquid required to moisten the paper towels
Time taken by the paper towels to become completely moist

Answer:
44.2 L
Explanation:
Use Charles Law:
We have all the values except for V₂; this is what we're solving for. Input the values:
- make sure that your temperature is in Kelvin
From here, we need to get V₂ by itself. To do this, multiply by 273 on both sides:
Therefore, V₂ = 44.2 L
It's also helpful to know that temperature and volume are linearly related. So, when temperature drops, so will volume and vice versa.
