Thorium is a solid at r.m.
Frozen
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.
20 degrees Celsius = 68 degrees Fahrenheit 30 degrees Celsius = 86 degrees Fahrenheit.
20 degrees Celsius = 68 degrees Fahrenheit.
(-20) degrees Fahrenheit = -28.8 degrees Celsius.

20 degrees Celsius is colder
20 degrees Celsius = 68 degrees Fahrenheit 30 degrees Celsius = 86 degrees Fahrenheit.
-20 degrees Fahrenheit = -28.89 degrees Celsius
-20 degrees Fahrenheit converts to -28.9 degrees Celsius.
20 degrees Celsius = 68 degrees Fahrenheit
-20 degrees celsius is -4 degrees fahrenheit.
