Question

An ice cube is suspended in vacuum in a gravity free hall. As the ice melts it
(a) will retain its cubical shape
(b) will change its shape to spherical
(c) will fall down on the floor of the hall
(d) will fly up.

Answer 1

Answer:

b

Explanation:

after melting it turns into water . when water is in vacuum it turns into spherical . because force is acting from all sides. please mark me as a brain list

Answer 2

An ice cube is suspended in vacuum in a gravity free hall. As the ice melts it will change its shape to spherical.

Explanation:

• When there is a melting of ice cubes, the state of it changes to liquid from solid.
• There will be open surfaces in this melted liquid where the forces of surface tension come into effect.
• The forces on the surface tension tend to reduce the surface area. In a gravity-free hall, the melted ice cube can be found, which has open surface all around.
• By getting a spherical shape, the minimum surface area can be achieved.
