Every material exists in liquid state exatly when its temperature is BETWEEN its melting point and its boiling point. Now -140°C is between -169 and -104 so the ethene at -140°C is in liquid state. -140°C is also between -185 and -48 so the propene at -140°C is also liquid. Same for pentene. The butene at -140°C is solid because -140°C is BELOW its melting point -138. So exactly 3 substances are liquid at -140°(, while the butene is solid at -140°C.Log in to reply
