Not even a change at all. My chemistry teacher always told us, if you can't reverse it so that the product will be identical as before it's a chemical reaction. I.e. Melting a Chocolate bar, it can solidify but not exactly the same (shape and whatnot) as before, or exploding, not even reversible.
No it is not. The chemical composition is H2O before and after freezing.
The formation of icicles at the edge of a roof is a physical change. It occurs when water freezes due to a drop in temperature, without any change in the chemical composition of the water molecules.
Icicles is solid water (H2O); formation of ice is a physical process.
The formation of an icicle on the roof is a physical process. It occurs when water freezes due to the temperature being below freezing point, leading to the solidification of the liquid water into ice.
Yes, lightning can strike through a roof if the building is not properly grounded or protected by a lightning rod. Metal components such as wiring, pipes, or structural elements can conduct the electrical current from a lightning strike, potentially causing damage or fire. It is important for buildings in areas prone to lightning strikes to have proper lightning protection in place.

the first baseball tea to have a roof was the philadelphia flyers the first baseball team to have a roof was the philadelphia flyers
Yes
If the ball that is currently in play strikes any inanimate object, it is considered out, and so the opponent wins the point.

To change the roof Ariel on Vauxhall Zafira you need a genuine replacement and the user manual.
