So so confused uh jus listen to the other answer aha
Explanation:
A freezing point is defined as the point in which a liquid state of a substance changes into solid state.
Whereas boiling point is defined as the point at which liquid state of substance starts to convert into vapor state.
So, a substance is freezing at 
and boils at 
then it means at room temperature, that is, around 
the substance is present in liquid state.
This is because between the freezing and boiling point a substance will always exist in liquid state.
Thus, we can conclude that state of the material at room temperature is liquid.
Explanation:
The driving force behind plate tectonics is convection in the mantle. Hot material near the Earth's core rises, and colder mantle rock sinks.
Consider the amount of energy needed to brake the bonds.
In c=o there are both a pi-bond and a sigma bond. Therefore it requires a higher energy to brake it. When considering the c-o bond there is only a single sigma bond is needed to be broken. Therefore braking is easier.
When something is easily broken they are having a weak attraction. When they harder to break they are having a stronger attraction.
Here weak attraction is having a lower energy while stronger attraction has higher energy.
Therefore c=o provides a high energy than c-o
Answer:
600 seconds, or 10 minutes
Explanation:
300m/ 0.5m = 600s
