An Endothermic Reaction occurs when the energy used to break the bonds in the reactants is greater than the energy given out when bonds are formed in the products
An Exothermic reaction is one that releases energy in the form of heat or light.
</span>Exothermic Reactions: Rust and Setting of Cement
Endothermic Reactions: Photosynthesis and evaporation.
One example of an endothermic reaction is Ice packs. The packs that deliver instant cooling when a seal inside is broken. It works by having water and ammonium nitrate in separate compartments and then when you break the seal between them they mix. The reaction is endothermic so it takes in heat from the surroundings so the pack become cold.

Answer : The pressure it exert under these new conditions will be, 87 atm
Explanation :
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 19 atm
= final pressure of gas = ?
= initial volume of gas = 100 L
= final volume of gas = 20 L
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:
Therefore, the pressure it exert under these new conditions will be, 87 atm
