Question

This graph shows the phase change for water.

Temperature

\begin{tikzpicture}[scale=0.8]
\draw[<->] (0,0) -- (5,0) node[right] {Energy};
\draw[<->] (0,0) -- (0,4) node[above] {Temperature};
\draw (0,1) -- (1,1) node[midway,above] {A};
\draw (1,1) -- (2,2) node[midway,above] {B};
\draw (2,2) -- (3,2) node[midway,above] {C};
\draw (3,2) -- (4,3) node[midway,above] {D};
\end{tikzpicture}

Which section of this graph would represent the liquid state of water?
(1 point)

A
B
C
D

Answer 1

The liquid state of water is represented in section **C** of the graph. This section indicates a constant temperature (the water remains in the liquid state) while energy is added, which corresponds to water being in its liquid phase.
