I hope this helped :3
While ice melts, it remains at 0 °C, and the liquid water that is formed with the latent heat of fusion is also at 0 °C. The heat of fusion for water at 0 °C is approximately 334 joules per gram, and the heat of vaporization at 100 °C is about 2,230 joules per gram. So it will be C
Answer: Because of the its assumption of earth being at the centre of the universe and also, its parallax argument.
Explanation: Geocentric model is the
theory of the structure of the solar system (or the universe) in which Earth is assumed to be at the centre of it all. It was generally accepted until the 16th century, after which it was superseded by heliocentric models
Among many, geocentric model was considered because of its stellar parallax argument.
What is parallax? Parallax is the apparent change in position of objects due to a change in observation location
The ancient Greeks claimed that if the Earth is moving around the Sun then the stars should shift their positions due to this orbital motion (called stellar parallax). The stars don't shift. They don't shift enough for you to notice, but they do indeed shift. This is essentially the same reason the moon appears to follow you around when you drive - it's too far away for any apparent shift due to your motion.
Mass - the answer is mass. Since I need to write a bit more, the answers are not density, weight, gravity, size or anything like that!
Answer:
Exothermic Reaction
Explanation:
<u>ENDOTHERMIC REACTION</u>: A chemical reaction is considered endothermic if the energy is absorbed during the reaction. In other words, if the energy is required by the reactants to proceed with the reaction, then the reaction is endothermic.
The value of enthalpy change ΔH is positive in such reactions showing intake of energy.
<u>EXOTHERMIC REACTION</u>: A chemical reaction is considered exothermic if the energy is released during the reaction. In other words, if the energy is produced as a product of the reaction, then the reaction is exothermic.
The value of enthalpy change ΔH is negative in such reactions showing the release of energy.
Since, the value of ΔH = -125 KJ, is negative for the given reaction.
Therefore, it would be considered as <u>Exothermic Reaction.</u>
