What type of change is ice melting? (without salt)
A. Chemical
B. Physical
I chose A.
B. Physical
Explain your answer in 1-2 sentences.
Ice melting is a physical change because it involves a change in the physical state of water from a solid to a liquid, without any change in its chemical composition.
Thank you. By the way it's still me!
You're welcome! If you have any more questions, feel free to ask.
The correct answer is B. Physical. Ice melting is a physical change, not a chemical change.
To determine the type of change, we need to understand the difference between physical changes and chemical changes.
Physical changes involve a change in the physical properties of a substance, such as shape, state of matter, size, or phase, but the identity of the substance remains the same. In the case of ice melting, it changes from a solid state to a liquid state, but its chemical composition (water molecules) remains the same.
On the other hand, chemical changes involve a transformation in the chemical composition of a substance, resulting in the formation of new substances with different properties. Examples of chemical changes include burning, rusting, or decomposition of a substance.
In the case of ice melting without the addition of salt or any other substance, it is a physical change because the ice is simply changing from a solid to a liquid state, without any alteration in its chemical composition.
