QUESTION 7 Why is the temperature of water more stable than temperature of air? O Water has a higher density water has a higher specific heat water has a higher viscosity water is more stuborn QUESTION 8 Large animals have high fitness for cold climates because? because they can eat a lot of food They have a low surface to volume ratio They have high surface to volume ratio O because they can not hibernate during the year QUESTION 9 Why is soil with a large amount of clay a blessing and curse for plants? 310 29

Explanation / Answer

Dear student,

you are correct for both questions.

Ans7

water has higher specific heat capacity than air. Thus water can hold more heat than air and remain more stable.

Thus , (b) is correct- water has high specific heat capacity.

Ans 8

In colder climates, animals need to produce more heat and reduce loss of body heat . For animals with larger surface area, more heat will be lost. But animals with low S.A to volume ratio looses less heat (due to low S.A) and produces more body heat (due to large volume).

Thus , (b) is correct. They have a low surface area to volume ratio.
