T ( t ) = C e k t + T m where Tm is the temperature of the surroundings 
T ( t ) = C e k t + T m
T ( 0 ) = 20
T ( 1 ) = T ( 0 ) + 2 = 22
C + T m = 20 C+Tm=20

Describe the movement of particles at the melting point of a substance
Rasek [7]

Answer:

Melting occurs when a solid is heated and turns into a liquid. The particles in a solid gain enough energy to overcome the bonding forces holding them firmly in place.

During the melting point, the particles start to move about, staying close to their neighboring particles, then move more freely.

Explanation:

As a substance melts and goes from a solid to a liquid state, the kinetic energy of the molecules increases and moves faster, and separates further away from each other. This is why a liquid can fill the shape of its container, where a soild has a fixed shape.
