Answer:

Following are the responses to the given choices:

Explanation:

  • Air woods is a smoking process as it releases heat.
  • Incasereaction produces reaction energy, the response is then exothermic, while absorbs react energy, therefore the response is exothermic.
  • Heat is essential for melting ice. Correspondingly, ice melts into liquid water as well as other reactions stop.
  • Feel cold due to fuel absorption. That ice pack thus feels cold and brings another micro reaction to the stop.
  • Unless the reaction's heat is positive, that process is endothermal.
  • The reaction is exothermic unless the heat from the reaction is bad.
  • Feel hot due to its loosening energy. A test tubefeelhot is, thus, an exothermic reaction.
