Question

Enny wants to find out which frozen solid melts the fastest: ice, soda or orange juice. She pours each of the three liquids (water, soda and orange juice) into the empty cubes of an ice tray and then places the ice tray in the freezer overnight. The next day, she pulls the ice tray out and sets each cube on its own plate. She then waits and watches for them to melt. When the last part of the frozen liquid melts, she records the time1.

Which frozen solid melts the fastest?
a) Ice
b) Soda
c) Orange juice

Answer 1

Option a) pure ice likely melts faster than soda or orange juice due to the absence of solutes that lower the freezing point and require additional energy to melt.

Step-by-step explanation:

Jenny wants to determine which frozen solid—ice, soda, or orange juice—melts the fastest. Given that all substances begin at the melting temperature of 0°C, the melting process involves a phase change where the solid form (ice) transforms into liquid water at this temperature. Once the phase change occurs, the temperature of the liquid will begin to rise. However, in comparing ice, soda, and orange juice, the differences in the specific heat and the presence of sugars and other solutes in the soda and orange juice can affect the rate at which these frozen solids melt. option a) Pure ice (water) is likely to melt faster because the presence of solutes in soda and orange juice lowers their freezing point, which means they will require more energy (heat) to melt when compared to pure ice.
