Answer 1

B.) More intensely

Step-by-step explanation:

If you immerse a lightstick in hot water, the chemical reaction will speed up. The stick will glow much more brightly but will wear out faster too.

Answer 2

Answer: Option ' B ' is correct.

Step-by-step explanation:

When we drop a light stick into hot water , it glow more intensely.

Because in warm water, chemical reaction may occur faster as compare to in cold water.

Chemical reaction in hot water is faster due to which light stick glow much brighter.

To make the light stick last longer, chemical reaction needed to be slower for that it must be kept in freezer or in colder place.

Hence, Option 'B' is correct.
