What i would say: The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds. Gravitational potential energy increases as weight and height increases.
Hope this helps! :)
1 cm of copper. This is because copper atoms are heavier than aluminum atoms.
Answer:
3.0585147719047385 is the answer
Explanation:
When heat is absorbed by reactants in a chemical reaction then the reaction is known as endothermic reaction.
Whereas when heat is released by reactants in a chemical reaction then the reaction is known as exothermic reaction.
1. When
is positive then it means heat is absorbed by reactants and reaction is endothermic.
2. When
, this means energy of products is less than the energy of reactants. Therefore, it is exothermic in nature.
3. When energy is absorbed then reaction is endothermic.
4. When
, this means energy of products is greater than the energy of reactants. Therefore, it is endothermic in nature.
5. When [tex]\Delta H is negative then it means heat is released by reactants and reaction is exothermic.
