Answer:
An endothermic process is any process with an increase in the enthalpy H (or internal energy U) of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system. It may be a chemical process, such as dissolving ammonium nitrate in water, or a physical process, such as the melting of ice cubes.
Balancing the equation, we get:
2C₂H₆O + O₂ → 2C₂H₄O₂ + 2H₂O
So
α = 2
β = 1
γ = 2
δ = 2
Answer: This is true because kinetic energy depends on speed. If there's no speed, then there is no kinetic energy.
