What happens to an object that weighs more than water?

• A. It sinks
• B. It floats
• C. It evaporates
• D. It dissolves

Answer: (A)

An object that weighs more than water will sink because of the principle of density. This principle states that an object will float if it is less dense than the fluid it is placed in and will sink if it is denser. When an object has a weight greater than the weight of the water it displaces, the buoyant force exerted by the water cannot support the object, leading it to descend to the bottom. This is a fundamental concept in physics related to buoyancy and density, which is crucial for understanding how materials interact with fluids. The other possibilities do not apply in this context. Evaporation refers to a change from liquid to gas, which is irrelevant to the behavior of physical objects in water. Dissolving involves a chemical interaction, where a substance breaks down in a solvent, which does not occur simply based on weight. Floating only occurs when the object is less dense than the water.
