When a lake is frozen and the temperature is -30 degrees outside. How many degrees is the water unter the ice is it 0 Under the ice the water doesn't move. Why the lake is not frozen completely?

The short answer is that high pressure air "sinks." The air at the centre of a ridge or dome of high pressure travels downward from a higher, cooler altitude to the relatively warmer layer near the earth's surface. The journey from cooler to warmer causes the moisture in the air to evaporate, and become invisible to the eye. The opposite happens in an area of low pressure. The air rises and cools. This causes condensation which results in clouds. When the condensation is too heavy to defy the law of gravity, we get precipitation. Hope that helps.

Does the element mercury harden?
no it doesnt -_- Mercury will freeze (become a solid) at -38.83 degrees Centigrade or -37.89 degrees Fahrenheit.
How hot is the mantle of the earth?
Earth's mantle reaches temperatures of about 3700°C.
What temperature can water turn into a thin layer of ice?
All water starts to turn to ice at 0 degrees Celsius or 32 degrees Fahrenheit. it just depends how long you leave it to freeze. it usually takes about half an hour for a very thin layer of ice to appear on the top however it doesnt just freeze at the top, it freezes on the whole outside of the water so even if the top is a thin layer of ice after about an hour, there is a high chance that it is also frozen the whole of the outside to form like an ice container however the ice is very weak and even slightly touching it will cause it to break. hope this helps :)
How does rain affect air temperatures?
rain doesnt actualy change the temperature although it may feel like it
Why doesnt the water end up at the center of the earth besides the fact the it would turn to water vapor due to the increase in temperature?
Water is lighter than rock (and especially iron and heavy metals that make up the core), so it really wants to be displaced. The high temperature also creates a high vapor pressure, encouraging it to leave as well.

The correct temperature is 40-45 degrees, make sure it doesnt get much hotter!

To make sure whatever you are heating doesnt get above the temperature of steam (~100 degrees C).

Why doesnt liquids stay solid?
it is because of of room temperature Every substance has a particular temperature it has to be before it changes from one state of matter (gas, solid, and liquid) to another. For example, water changes from ice(solid) to liquid water when it's temperature rises above 0 degrees Celsius (32 degrees F), and it changes from a liquid to water vapor (gas) when it rises above 100 degrees Celsius (212 degrees F). The temperature different liquids require to change to either solid or gas depends on the particular liquid's freezing/boiling point.
