Ice at a temperature of $0^{\circ}\text{C}$ is an unusual solid because it floats on its liquid form, water, when both are at the same temperature. What explains this?
- AThe average speed of the molecules in the ice is greater than the average speed of the molecules in the water.
- BThe average speed of the molecules in the water is greater than the average speed of the molecules in the ice.
- CThe mean separation of the molecules in the ice is greater than the mean separation of the molecules in the water.
- DThe mean separation of the molecules in the water is greater than the mean separation of the molecules in the ice.
