Question

The melting point of two substances A and B are 280 kelvin and 320 kelvin respectively are these substances liquid at room temperature ? justify your answer

Answer 1

Standard room temperature is 298 K. So melting point below 298 K will be liquid at room temperature so 280 K will be liquid at room temperature while 320 K will be solid.. So if the melting point of substance is below 298k then it is liquid and if the melting point of substance is above 298k then it is solid.
