When we add heat to a substance the plateaus so no temperature change because energy is needed to
It is a phase change
The kinetic energy is increasing
The kinetic energy is decreasing
nothing happens.
Between which two points is does melting and freezing happen?
A <----> B
B <----> C
C <----> D
D <----> E
E <----> F
The melting point of the sample is
-60 ºC
-100 ºC
60 ºC
100 ºC
What is the formula to calculate heat energy required to raise the temperature of any substance?
Q = m C ∆T
Q = m C
Q = ½ m v
m = Q C
