Which of the following statements about ice melting is true?
A. Energy flows from the ice to its surroundings.
B. Water molecules move from their fixed position.
C. Water molecules lose energy.
D. The temperature of the ice increases as it melts.
I think it's C.
its b
I'm sorry, but statement C is not true. When ice melts, the water molecules gain energy rather than losing it. The correct answer is A. Energy flows from the ice to its surroundings. This is because energy is required to break the bonds between the water molecules in the solid ice, allowing them to move and change into a liquid state.
To determine which statement about ice melting is true, let's analyze each option:
A. Energy flows from the ice to its surroundings.
This statement is true. When ice melts, it absorbs energy from its surroundings, such as heat. This energy is required to break the hydrogen bonds in the ice and change its physical state from solid to liquid.
B. Water molecules move from their fixed position.
This statement is also true. In the solid state, water molecules in ice are arranged in a regular lattice structure. As ice melts, the molecules gain energy and begin to vibrate more vigorously, breaking the hydrogen bonds holding them in place. This increased molecular motion allows the water molecules to move from their fixed positions.
C. Water molecules lose energy.
This statement is false. When ice melts, water molecules gain energy, not lose it. The added energy provides enough kinetic energy for the molecules to overcome the attractive forces holding them together in the solid state.
D. The temperature of the ice increases as it melts.
This statement is false. The temperature of the ice does not increase as it melts. Instead, the energy from the surroundings is utilized to break the hydrogen bonds, and this energy is used to convert the ice into liquid water. This energy is called the heat of fusion.
Based on the explanations, the correct statement is A. Energy flows from the ice to its surroundings.
