A lake is not a liquid, it's the water in it that is a liquid.
A lake which remains in a liquid form although it is covered with ice is called an ice covered lake.
In a freshwater lake or ice
The water found in a lake is in the liquid state of matter. In this state, water molecules are closely packed together but can move freely, allowing the liquid to flow and take the shape of its container. Depending on the temperature, lake water can also exist in solid (ice) or gas (water vapor) states, but the predominant state is liquid.
Asphalt is a sticky, black and viscous liquid present in most crude petroleum's. There is a Pitch Lake in Trinidad, La Brea Tar Pits in California, and Guanaco Lake in Venezuela
Evaporation. Condensation is when water vapor leaves the gas state and becomes liquid again. Evaporation is when liquid water moves into the gas state. Precipitation is water (as liquid or solid) condenses and falls from clouds. Runoff is solid water turning to liquid. So of those four, only evaporation could be described as water coming from the lake... unless the lake is frozen solid - then it could be runoff.
Google states that the volume of Lake Michigan is about 1,180 cubic miles which equals 1,299,318,234,000,000 gallons [US, liquid]
When Frozen water floats on liquid water
Yes, whenever something changes from liquid, solid or gas, It is considered a change in state.
A reservoir is a stored quantity, generally of a liquid or gas. The bulb on a thermometer is a reservoir. A lake is a reservoir.
The fact that ice floats means that the lake probably will not freeze solid all the way down. There will still be liquid water at the bottom of the lake where the fish can stay alive all winter.
The damage that cannot be repaired in a Liquid Fertilizer Spill would be, you cannot fix the habitat of a home, in the water/lake, and you cannot repair your night with your mom.
The evaporation of water in a lake is a physical change. This is because the water is changing state from liquid to gas without any change in its chemical composition.
