Volume (V) — heating gives particles more kinetic energy and (if the object is free to expand) it expands.
Mass (m) stays essentially the same for a closed system, so density D = m/V goes down when V increases. Caveats: if the object is held at fixed volume (rigid container) the pressure rises instead, and some substances (notably water between 0 and 4 °C) show anomalous behavior.
