Iron is a solid at 20 oC. We would be in a lot of trouble if it weren't, all our cars would become a pool of liquid.

To amplify a little, we are fairly comfortable or a bit warm at 20ºC because it equals 68ºC.
Incidentally, on my PC at least, the degree sign ( º ) is given by the [ALT]+0186 combination, using the calculator pad not the top row keys. Just a tip others might find handy but it might depend on your own computer's settings!
Mercury turns to a liquid at 25 degrees Celsius.
25 degrees Celsius = 77 degrees Fahrenheit
25 degrees Celsius = 77 degrees Fahrenheit.
25 degrees Celsius is equivalent to 77 degrees Fahrenheit.
Iron melts at 1536 °C or 2797 °F (1811 K). It boils at 2862 °C or 5182 °F (3134 K).
The state of water at -25 C is solid. Water freezes at 0 degrees Celsius.
Phenol is a solid at room temperature (25°C). It has a melting point of 40.5°C, so at 25°C, it would exist in a solid state.
Mercury is a liquid at 25 degrees Celsius.
At 1000 degrees Celsius, iron is in its molten state, which means it is a liquid. This is above its melting point of approximately 1535 degrees Celsius.
gaseous
Solid.
Pure oxygen is a gas at 25 C, regardless of the pressure.
Xenon is a noble gas and it exists as a gas at room temperature (25 degrees Celsius).
25 degrees C = 77 degrees F
The difference between 25°C and -18°C is 43 degrees. This means that 25°C is warmer than -18°C by 43 degrees.
Zinc is a solid at 25 degrees Celsius. It has a melting point of 419.5 degrees Celsius and a boiling point of 907 degrees Celsius.
At 25 degrees C the density of water is 1.0 g/mL. If the temperature of the water goes above 25 degrees C the density will drop. If the temperature of the water goes below 25 degrees C the density will rise.
