Answer:
yes something is contributed for science because today is the age of science
I dont know what subject is this
The process releases energy and consequently we classify it as exothermic. (d) a person running releases warmness as muscle mass paintings. therefore, the procedure is exothermic.
d) Exothermic, heat is released as a person runs and muscle groups perform work.
A chemical response or bodily exchange is exothermic if warmth is released by using the system into the environment. Because the surroundings are gaining heat from the system, the temperature of the surroundings increases. The sign of q for an exothermic procedure is -ve due to the fact the device is dropping heat.
Some other examples of exothermic reactions:
1)Snow Formation in Clouds.
2)Burning of a Candle.
3)Rusting of Iron.
4)Formation of Ion Pairs.
5)response of strong Acid and Water. etc...

#2 During chemistry lab, Mrs. Black’s students placed an antacid tablet in a zip lock bag. They recorded the mass of the tablet in the bag. Then they carefully added 50 grams of water and quickly sealed the bag. The tablet began to fizz and soon disappeared. The bag was filled with gas and it felt cold to the touch.
