Ethanol has a melting point of

-114 \, ^\circ\text{C}

and a boiling point of

78 \, ^\circ\text{C}

. A sample of ethanol is at

25 \, ^\circ\text{C}

. It is then cooled to

-130 \, ^\circ\text{C}

.

Which row correctly shows the physical state of ethanol at the two temperatures?

25 \, ^\circ\text{C}

-130 \, ^\circ\text{C}
