Question 12

A student is performing two experiments under standard conditions. In the first setup, a beaker containing solid paraffin wax is heated and is currently melting. In the second setup, a flask of pure liquid ethanol is heated and is currently boiling.

What is happening to the temperature of the melting paraffin wax and the temperature of the boiling ethanol?

A

Melting paraffin wax temperature is constant; boiling ethanol temperature is constant

B

Melting paraffin wax temperature is constant; boiling ethanol temperature is increasing

C

Melting paraffin wax temperature is increasing; boiling ethanol temperature is constant

D

Melting paraffin wax temperature is increasing; boiling ethanol temperature is increasing
