Taken in
- B
Give out to surroundings
- C
Neither given nor lost
- D
None of these
The correct answer is "heat is given out." In an exothermic reaction, heat is released or given out to the surroundings as a result the temperature of the system rises above the room temperature.
"Taken in" is incorrect because in an exothermic reaction, heat is not absorbed or taken in from the surroundings.
The correct answer is "heat is given out." In an exothermic reaction, heat is released or given out to the surroundings as a result the temperature of the system rises above the room temperature.
"Neither taken in nor given out" is incorrect because exothermic reactions specifically involve the release of heat energy
"None of these" is incorrect because one of the given options, "Heat is given out," accurately describes an exothermic reaction.
