MCQ
An ice cube is suspended in vacuum in a gravity free hall. As the ice melts it.
- AWill retain its cubical shape.
- ✓Will change its shape to spherical.
- CWill fall down on the floor of the hall.
- DWill fly up.
✓
Answer
Correct option: B.
Will change its shape to spherical.
As the ice cube melts completely, the water thus formed will have minimum surface area due to its surface tension. Any state of matter that has a minimum surface area to its volume takes the shape of a sphere. Therefore, as the ice melts, it will take the shape of a sphere.
