Question

At room temp., a substance with a melting point of 40% C is a?
solid, liquid, gas, mixture

Answer 1

At room temperature, a substance with a melting point of 40% C is a B Liquid

Answer 2

The substance will be a solid.

Step-by-step explanation:

Melting point means the temperature at which a substance goes from solid to liquid. For example, the melting point of water would be 0C, these means that at atmospheric pressure, water at a higher temperature than 0C will be liquid.

Now, room temperature, refers to the temperature that most people prefers for indoors. It is usually in a range between 20 and 22C. These means, the substance will be around the same temperature when thermodinamic equilibrium is reached. Therefore, the substance will be at a temperature lower than its melting point and it will be in solid state.
