A student heats a solid from

-10 ^\circ\text{C}

to

60 ^\circ\text{C}

. The temperature stays constant at

20 ^\circ\text{C}

for some time before rising again. What happens to the particles while the temperature is constant at

20 ^\circ\text{C}

?

Particles move slower and come closer together.
Particles gain kinetic energy and move faster in the solid.
Particles absorb energy to overcome forces of attraction and change to liquid.
Particles lose energy and change from liquid to solid.
