Answer:
Hypothesis, Ice is less dense then water.
Explanation:
They could test this by attaining the density of ice and water, the density of Water is 1g/ml and if the ice floats that means ice is less then 1 g/ml which means ice is less dense. This is relevant to the water bottle because the Ice expanded due to it being less dense causing the water bottle to rupture
The physical characteristics that determine the exhistance of organisms in aquatic enrironments relate to its pH (which is whether it's acid, neutral or basic), the water clearance (which refers to the particles diluted in it, the presence of toxic substances, etc), the presence of predators (bio chain) and also if there's enough food for the organisms to live, to reproduce and if the water temperature allows them to subsist or if they need to migrate within a year, due to the natural changes.
