A principle difference between a liquid and a gas is that when a liquid is under pressure, its volume [increases] [decreases] [doesn't change noticeably] and its density [increases] [decrease] [doesn't change noticeably]. When a gas is under pressure, its volume [increases] [decreases] [doesn't change noticeably] and its density [increases] [decreases] [doesn't change noticeably].

Textbook Solutions for Practicing Physics for Conceptual Physics
Chapter 14 Problem 3
Question
A hydrogen-filled balloon that weighs 10 N must displace ____ N of air in order to float in air. If it displaces less than N it will be buoyed up with N and sink. If it displaces N of air it will move upward.
Solution
The first step in solving 14 problem number 3 trying to solve the problem we have to refer to the textbook question: A hydrogen-filled balloon that weighs 10 N must displace ____ N of air in order to float in air. If it displaces less than N it will be buoyed up with N and sink. If it displaces N of air it will move upward.
From the textbook chapter Gases and Plasmas you will find a few key concepts needed to solve this.
