Fill in the blank. The temperature at which matter changes from the solid state to the liquid state is known as its blank point. (A) Critical, (B) melting, (C) boiling, (D) drying, (E) freezing.

Matter can exist as a solid, a liquid, or a gas. The state of matter can be changed by adding or removing energy, which we can think of as increasing or decreasing the temperature. To discuss these changes, let’s consider water in its solid, liquid, and gaseous form.

When solid ice is at a temperature of zero degrees Celsius, the ice will begin to undergo the process of melting and will turn into liquid water. The temperature at which matter begins to change from the solid state to the liquid state is known as its melting point. When the temperature of liquid water is 100 degrees Celsius, the water will begin to boil and turn into water vapor, water in its gas state. The temperature at which matter begins to change from the liquid state to the gas state is known as its boiling point.

The question has to do with the temperature at which matter changes from the solid state to the liquid state. We know that the temperature at which this change occurs is called the melting point. So we should fill in the blank with the word “melting,” answer choice (B), so that the statement reads “The temperature at which matter changes from the solid state to the liquid state is known as its melting point.”
