Answer:
<em>Plane Motion</em>
<em>Plane Motion One of the most common examples of motion in a plane is Projectile motion.</em>
Alcohol filled thermometer is used for low temperature applications. (Weather) It’s freezing point is -70 degC
While mercury freezes at -38 deg C
Mercury is/was better for human and other animal temps. High thermal coefficient of expansion mercury vs. alcohol = better resolution for small temperature changes in a medical application.
For higher temperatures alcohol will boil before mercury will.
Answer:
4Al + 3O2 + heat ------> 2Al2O3
Explanation:
It is endothermic reaction.
Due to the decay of naturally radioactive substances, or even due to the heat made by the movement of the tectonic plates, and formation of gravitational acceleration, the temperature increases.
