What happens when the temperature of an object increases?
The particles move closer together.
The particles move faster.
The number of particles increases.
The particles stop moving.
C, D are wrong as
C: the heat flows from the object with higher temperature to lower temperature
D : would have been right if it was specific potential energy
A) The average kinetic energy of their particles is the same. (right)
B) It would have been the same if m was
THE PARTICLES MOVE FASTER
that is what i thought
let me first guess
To remove a tight-fitting lid from a jar, Megan runs the lid under hot water. What happens to the jar lid when its temperature increases?
The potential energy increases, and the lid contracts.
The potential energy decreases, and the lid expands.
The temperature increases, and the lid expands.
The temperature decreases, and the lid contracts.
