What is the physical state of propane at its melting and boiling point? Solid, liquid, or gas

I know that propane is a gas at room temperature.
I also know that the melting point of propane is -190 degrees C and the boiling point is -42 degrees C.
Can someone please help me by telling me what state propane is at while it hits its melting and boiling point? Thanks for all those who help! :)

At its melting point propane should be solid,after the bonds are broken and temperature increases then it goes to liquid
At its boiling point propane is liquid....temperature stays the same as bonds are broken and then increases as it goes to gas.
