Answer:
What information can climatologists learn from fossils? Fossils of plants and animals can show adaptations that organisms had for a particular type of climate that existed millions of years ago. Climatologists look at many pieces of evidence to study climate change. These pieces of evidence can support each other.
Explanation:
,.,
Fireworks
An exothermic reaction is one where the products have lower energy than the reactants, so the reaction yields energy. The chemical compounds present in firework fuel release a lot of energy upon oxidation. Photosynthesis is endothermic, settling of silt is not a chemical reaction, it is a physical change. Finally, the bubble formation in soda is not exothermic; otherwise, the sodas would become very hot very fast.
Answer:
Explanation:
Hello,
In this case, as the copper's heat loss is gained by the water, the following energetic relationship is:
Therefore the equilibrium temperature shows up as:
Thus, by knowing that water's heat capacity is 4.18J/g°C, one obtains:
Best regards.
Answer:
Three types of metamorphism exist: contact, dynamic, and regional. Metamorphism produced with increasing pressure and temperature conditions is known as prograde metamorphism.
