Is that the full question?
Answer:
Radioisotopes are radioactive isotopes of an element. They can also be defined as atoms that contain an unstable combination of neutrons and protons, or excess energy in their nucleus.
Explanation:
False.
Heat speeds up the motion of particles when it is added to the object/substance the atoms loosen up and move/vibrate faster and more. But when subtracting heat from the object/substance, the atoms move/vibrate slower. This is called the Kinetic theory of matter.
