Answer:
Mass does not change based on gravity
Explanation:
Mass is how much matter is in an object. That's why we have the same mass on Moon, Neptune, etc.
But weight depends on gravity. That's why our weight on the moon is less than Earth because the Moon's gravity is less than Earth.
This would be the stratosphere. which is the second layer of the atmosphere.
The synthesis of a compound from its elements in their standard state, accompanied by a change in energy that is known as standard enthalpy of formation of a compound. The standard state of a substance is the most stable physical state of the compound that exist at STP that is at 1 atm, 273 K temperature. So the answer is yes, the energy change accompanying the synthesis of a compound from its elements in their standard state.
