Answer 1

Answer:

(a) Exotherms

Explanation:

The upward peaks of DTA curve indicates EXOTHERMIC PEAK

Answer 2

The upward peak in the DTA curve indicates exotherms.

• In DTA or Differential thermal analysis technique, the temperature difference between the test sample and inert reference sample under controlled and identical conditions of heating and cooling is recorded continuously as a function of the time or temperature.
• In the DTA curve, the upward peak indicates exotherms and the downward peak indicates endotherms.
• Hence the correct option is a.
