Water freezes at 0 degrees Celsius
Water at -20 degrees Celsius; heat will expand matter, so at +40 degrees Celsius, water would have less density. * * * * * That would be true if there were no phase change. Unfortunately for the above answer, water freezes at 0 deg C and that phase change is accompanied by an expansion. As a result, water at 40 deg C is denser that water (ice) at -20 deg C.
Mercury is a liquid at 500 degrees Celsius. It has a melting point of -38.83 degrees Celsius and a boiling point of 356.73 degrees Celsius.
At 500 degrees Celsius, mercury is in its liquid state. Mercury has a melting point of -38.83 degrees Celsius and a boiling point of 356.73 degrees Celsius, so at 500 degrees Celsius it would be in its liquid form.

There is not a constant difference. At the freezing point of water, 0 deg Celsius = 32 deg Fahrenheit - a difference of 32. At the boiling point of water = 100 deg C = 212 deg F, the difference is 180.
At minus fifty degrees Celsius, water is in solid form, known as ice. This is because water freezes at 0 degrees Celsius.

On the Celsius scale, pure water, at normal atmospheric pressure, freezes at 0 deg C and boils at 100 deg C.
