According to the cooling curve given above, at temperature 275K, the phases that will be observed is LIQUID AND SOLID.
The flat points on the graph represent the points where phase changes are taking place.The beginning of the first flat point represent the point where the gas become liquid, the extreme end of this point indicate the point where the liquid has started turning to liquid and that is the point of 275K. Thus at that point both phases are present.
Answer:
"Acids produce hydrogen ions, H+, in water. Bases produce hydroxide ions, OH-."
Explanation:
<h2>The required "option is b) potential energy".</h2>
Explanation:
- The energy which is associated with the motion of the object is called kinetic energy.
- The energy which is associated with the amount of heat released is known as thermal energy.
- The energy which is released during a chemical reaction is known as chemical energy.
Therefore, option (a), (c), and (d) are incorrect.
- The energy which is possessed by a stationary object or associated with the position of an object is called as potential energy.
- Hence, the correct option is potential energy.
Answer:
well it could be mars
Explanation: it closer so its hotter but also there not almost the same
