Cobalt chloride paper demonstration:

1. The cobalt chloride paper test is a simple way to assess a plant's transpiration rate.
2. To conduct the test, blue-colored dry cobalt chloride paper is used.
3. Blue cobalt chloride paper changes its color into pink when exposed to water.
4. It allows the rate of transpiration to be determined by the time it takes for the paper to change color from blue to pink.

Final answer: The given statement ‘Calcium chloride paper is used to demonstrate transpiration’ is false.
