And before I get yelled at for having such a liberal definition of solute (which I admit, is a bit foolish!), knowing this number is important when your actual solute (not water) changes the volume of the solution and especially in a nonlinear fashion. 1  permalink. 2  embed. 3  save. give gold.
Better Than the Elevator. The website HealthStatus notes a person who weighs 160 pounds burns about nine calories during a minute of walking up a set of stairs. During the same activity, a 210-pound person burns about 12 calories. If climbing a flight of stairs takes you about 30 seconds, expect to burn half the above calories. While this calorie burn might seem low, standing in the elevator for a minute burns about one and two calories, respectively, for the two people.
Walking Calorie Burn Rates. How many calories you burn when walking will depend on your speed, the terrain and your size. A slow, 2-mph pace burns 204 calories per hour for a 180-pound person. But, if that person doubles the speed to cover four miles in an hour, she can burn 409 calories. Take the walk uphill for the entire hour, and burn 490 calories. Smaller people burn fewer calories -- a 125-pound person uses 270 calories in an hour long, 4 mph walk. Larger people burn more -- a 185-pound person burns 400 calories walking for an hour at 4 mph.
