Yes. When snow melts H2O changes from a solid state to a liquid state
Yes
Yes.
It is a Physical Change. Melting it does not change what components/elements are found in snow. It is just a phase change from solid to liquid.
yes
yes it is. because you can freeze it and melt it
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.
No it is not .
Melting solid ice into liquid water is a physical change. It involves a phase change from solid to liquid without altering the chemical composition of water molecules.
Melting of gold for jewellery making is a physical change as no new substance is formed after melting. Changes in state or phase are physical changes.
Yes. Rain is pretty effective at melting snow.
Yes, melting snow is reversible. When the temperature drops, the melted snow can refreeze and turn back into ice or snow. This process is known as refreezing.
Yes, energy is required for each phase change. During a phase change, such as melting, vaporization, or sublimation, energy is either absorbed or released in order to break or form intermolecular forces between molecules.
