Question

The diagram shows a heating curve for water.


Which statement best describes what is happening at segment W-X?

Water is absorbing heat.
Water is releasing heat.
A liquid is changing to a gas.
A gas is changing to a liquid.

Answer 1

Water is absorbing heat.

On a heating curve, a phase change is indicated by a straight line.  Since W-X is sloped, the answer cannot be "a liquid is changing to a gas" or "a gas is changing to a liquid".  We know water is absorbing head on W-X because the line goes up, and the y-axis is rising temperatures.

Hope this helps!!

Answer 2

Statement A best describes what is happening at segment W-X. When the temperature is increasing, the curve is the linear increasing curve.

What is temperature?

Temperature directs the hotness or coldness of a body. In clear terms, it is the method of finding the kinetic energy of particles within an entity. Faster the motion of particles, more the temperature.

When the temperature is constant, the phase change process is occurred.

The temperature is increasing linearly with the temperature. The temperature is increasing from the 40 °C to 95 °C.

Hence, statement A best describes what is happening at segment W-X.
