The heat required to raise the temperature of a substance is given by the formula Q = C \( \times \)m\( \times \)\(\Delta \)T,where 鈥淐鈥� is the specific heat of the substance, 鈥渕鈥� is the mass of the substance, and 鈥溾垎T鈥� is the change in the temperature of the substance.

Since both the bottles contain water, the specific capacity of the water would be the same, which is 4.186 \(\frac{J}{{{g^0}C}}\).

The change in temperatures in both cases is also the same.

But the mass of the water is different. So the heat loss would be different in both cases. Therefore, the explanation given by the first student is incorrect.

A 2-L bottle of water loses more heat because there is more water. So, the explanation given by the second student is correct.

The mass of the water is greater for a bottle containing 2L of water. Since the mass of water is density times volume, the greater the volume, the greater its mass.

So, the explanation given by the third student is also incorrect.

The initial temperature is room temperature, and the final temperature is the refrigerator鈥檚 temperature. Since both the bottles are at the same temperature, the change in temperature in both cases is the same.

So, the explanation given by the fourth student is also incorrect.
