if an endothermic reaction begins at 26°C and decreases by 2°C per minute how long will it take to reach 0°C?

13 minutes

Explanation:

For the endothermic reaction to reach 0°C, it will take 13 minutes.

 Let us follow the process step by step;

 Rate of decrease is 2°C per minute.

  Start is 26°C

    Time                   temperature

     0 min                    26°C

      1 min                     24°C

      2 min                     22°C

     3 min                      20°C

    4 min                       18°C

   5 min                        16°C

     6 min                      14°C

     7 min                      12°C

     8 min                     10°C

    9 min                       8°C

     10 min                      6°C

     11 min                       4°C

     12 min                      2°C

      13 min                      0°C

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
