It is observed that the ice in Leah's glass of juice will melt first that the ice in Philip's glass of juice which sits on the table.
Step-by-step explanation:
It is given that Leah and Philip both have a glass of juice with ice cubes. Leah stirs her juice with her spoon. Philip let's his sit on the table.
Now, we need to answer whose ice cubes will melt first and why;
Firstly, let us assume that the ice is at a temperature of 0°C and the surroundings of the ice are at a temperature of 20°C.
Now, for the ice to melt, it should gain some energy from it's surroundings which can be transferred to the ice from it's surroundings by conduction through metal piece or a plastic piece.
We know that, metal is a best conductor as compared to plastic which means that the above-mentioned energy will be transferred more quickly through the metal as compared to plastic.
Furthermore, in the given condition, Leah stirs her juice with her spoon which we assume is of metal, proving the above-mentioned statements true.
Therefore, it is observed that the ice in Leah's glass of juice will melt first that the ice in Philip's glass of juice which sits on the table.
