When drivers fill up their tanks in Arizona or California, they see a dollar or more evaporate. The gasoline expands in the heat. So there's less energy in a tank of 100-degree gas than there is in a tank of 70-degree gas.

STEVE INSKEEP, host:

Arkansas is one of those states that gets a little toasty in the summer, and the heat may be ripping off the state's drivers. Gasoline evaporates, which is our last word in business today.

A new report says that when drivers fill up their tanks in Arizona or California, they see a dollar or more evaporate - disappear. The gasoline expands in the heat. So there is less energy in a tank of 100-degree gas than there is in a tank of 70-degree gas. Something to keep in mind as you drive around this holiday weekend.

And that's the business news on MORNING EDITION from NPR News. I'm Steve Inskeep.
