Question

When ice melts its particles:

• A. gain energy and begin to move
• B. lose energy and begin to move
• C. come close together and lose energy
• D. move very far apart and gain energy

Answer 1

The correct option is A gain energy and begin to move

The molecules in a liquid are not closely packed and have intermolecular space. To melt, ice energy is required. Heat is the form of energy supplied. On being heated the ice starts to melt because heat breaks the bond between the molecules and then the molecules are free to move apart. Thus, ice molecule gains energy and begin to move freely.
