Question

a group of scientists is researching a substance that improves the safe transportation of hydrogen when stored in a liquid. which of these is the best first step the scientists should perform? research conditions in which hydrogen can be stored in a liquid conclude which substances allow hydrogen to be stored in a liquid graph data about conditions that affect the feasibility of storing hydrogen test the effects different substances have on the feasibility of storing hydrogen

Explanation:

In scientific research, understanding the basic conditions for a phenomenon (in this case, hydrogen being stored in a liquid) is the first - step before making conclusions, graphing data, or testing substances.

Answer:

Research conditions in which hydrogen can be stored in a liquid
