Question

Question 5(Multiple Choice Worth 3 points) (03.01 MC) In an experiment, equal amounts of heated water and soil were left to cool down. The initial and final temperatures of each were recorded. A partial record of the temperature is shown. Experimental Record Substance Initial Temperature Final Temperature Water 27 °C 24 °C 27 °C Soil ? Which statement about the final temperature of soil is correct? O It will be less than 24 °C as soil loses heat relatively faster than water. O It will be less than 24 °C as water loses heat relatively faster than soil. O It will be more than 24 °C as it takes relatively longer to change soil temperature than water temperature. O It will be more than 24 °C as it takes relatively longer to change water temperature than soil temperature.​

Answer 1

The final temperature of the soil will be more than 24 °C because soil has a lower specific heat capacity than water, hence it retains heat longer.

Step-by-step explanation:

The question relates to the specific heat capacities of different substances. Water has a higher specific heat capacity than soil, meaning that water requires more energy to change its temperature. Given that equal amounts of heated water and soil were left to cool down and that the water cooled from 27 °C to 24 °C, then according to the experiment, which replicates the phenomena responsible for land and sea breezes, the soil would also cool down but would retain heat longer than water. Hence, the correct statement is: It will be more than 24 °C as it takes relatively longer to change soil temperature than water temperature.
