Explanation:

A point of temperature at which both solid and liquid state of a substance remains in equilibrium without any change in temperature then this temperature is known as melting point.

For example, melting point of water is 0 ^{o}C. So, at this temperature solid state of water and liquid state are present in equilibrium with each other.

Therefore, when a 100 g of given pure metal in solid state is heated at its exact melting point which is 215^{o}C then some of the solid will change into liquid state but the temperature will remains the same.

Why we need gravity explain in your own words​
Harlamova29_29 [7]

Answer:

Gravity is very important for us,animals and plants. We could not survive Earth without it. The sun's gravity keeps Earth in orbit around it, keeping us a good distance away from it (the sun). Gravity is holding down our atmosphere and the air we need to breathe along with it.

Our recorded observations are called.
trapecia [35]

Answer:  Raw data, perhaps.

Explanation:  I'm not certain what the question is seeking for an answer, but I would suggest "raw data" would be a reasonable choice.  It reflects the data was recorded, but not yet processed to provide a conclusion or observation.

If one were a bit snarky, other possiblities include

  • a pile of dung
  • my labmate's scrawls, or
  • the best web results I could find
