The image shows an experiment in which a student spills water on a wooden block and then places a beaker on it. The beaker
contains two powders: barium hydroxide and ammonium chloride. When the student mixes the powders, a liquid forms and
the beaker emits a gas with a pungent smell. Within a few minutes, the spilled water on the wooden block freezes to ice,
causing the beaker to stick to the block,
Why does the water freeze?
O A. The wooden block absorbs thermal energy from the water.
OB. The surrounding air absorbs thermal energy from the water.
C. The released pungent gas absorbs thermal energy from the water.
D. The reaction inside the beaker absorbs thermal energy from the water.
