sand burns the bottoms of their feet. Which of the following does NOT explain this experience?
SHOW CER
The sand absorbed heat from the sun and became hot

A student fills two cups with water and adds salt to one of the cups. The salt dissolves in the water. Then the student places identical blocks of wood in each cup. The block in the salt water floats, but the block in the pure water sinks.
Based on these observations, which statement correctly describes the density of the wood blocks?
SHOW CER
The blocks are less dense than the pure water but more dense than the salt water
The blocks are more dense than the pure water and the salt water
The blocks are less dense than the pure water and the salt water
The blocks are more dense than the pure water but less dense than the salt water.
