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.
According to one website, a 70-kg person (about 154 lbs) burns 10 calories per minute when ascending, and 7 calories per minute when descending, a flight of stairs. Therefore, if you climb up 10 sets of stairs (which will take an average of 5 minutes), you will burn 50 calories. That's more or less the equivalent of one slice of bread for a 5-minute workout. Pretty impressive.
