An iron block sinks in water because
Iron is heavier than water
Iron's density exceeds water's density
Iron does not displace water
Buoyancy is zero
Explanation
"Heavier" is ambiguous; what matters is <strong>density</strong>. Iron is denser than water, so its weight exceeds the maximum possible buoyant force (full submersion).
