To determine which evidence shows that the atoms that make up glucose have different properties than the molecule glucose, we can evaluate the provided options:

A. **Oxygen dissolves in water.** - While oxygen does have solubility properties, glucose's solubility in water is a separate property of the molecule itself rather than indicating a difference between the atom and the molecule.

B. **Carbon is a solid at 145 ° Celsius.** - This is relevant because it indicates that carbon, as an element, has a different state at a specific temperature compared to the melting point of glucose. This suggests that carbon’s properties differ from those of the glucose molecule.

C. **Hydrogen dissolves in water.** - This statement is not relevant to showing a difference in properties between hydrogen and glucose, as it does not directly compare the atomic properties to the molecular properties.

D. **Oxygen becomes a gas at negative 183 ° Celsius.** - This indicates that elemental oxygen has different physical properties (specifically, a state change at a different temperature) compared to the glucose molecule.

The best answer is **B** because it specifically indicates that carbon, as an individual atom, has a different state (solid) compared to glucose, which has a melting point of 146 ° Celsius. Thus, it shows a difference in properties between the atom and the molecule.
