What else can I help you with?
A change that occurs when a solid melts or a liquid freezes is an example of a phase change?
Yes, when a solid melts or a liquid freezes, it is an example of a phase change. This transition occurs due to a change in temperature, where energy is either absorbed (melting) or released (freezing) causing the particles to rearrange from a fixed position in a solid to a more fluid state in a liquid or vice versa.
How does a liquid change from a solid to a gas?
These are phase changes, ice melts into water and water evaporates into a gas.
When ice melts it gains energy and is call this type of change?
When ice melts it is called a physical endothermic change.
How does water change from gas to a liquid to a solid?
These are phase changes, ice melts into water and water evaporates into a gas.
Where do molecules go when ice melts?
The melting of ice is a change of phase, from solid to liquid, a physical processus. The molecules of water (H2O) remain unchanged during the change of phase.
Is melting of snow a phase change yes or no?
Yes. When snow melts H2O changes from a solid state to a liquid state
When a chocolate bar melts in the sun a physical or chemical change?
When a chocolate bar melts in the sun, it is a physical change. This is because the chocolate undergoes a phase change from a solid to a liquid without changing its chemical composition.
Explain what causes the phase change when solid iron melts into liquid iron?
We are trying to study for our test, and this is one of the study questions?
How does a solid change in to a liquid?
it melts
Silver melts at 961 Celsius Is it chemical change or physical change?
This is a physical change because you are changing it from a solid to liquid
What is the normal phase of iodine?
100c Is the normal Temperature for Iodine.
What is the change of entropy when an icicle melts at 2 degrees Celsius?
The change in entropy when an icicle melts at 2 degrees Celsius is positive. This is because the solid ice undergoes a phase change to become liquid water, increasing the randomness and disorder of the molecules, leading to a higher entropy.
