QUESTION 3
The specific heat capacity of aluminum is 0.22 cal/g °C. The specific heat capacity of water is 1.00 cal/g °C. If you heat a 100-gram aluminum pot containing 100 grams of water over the stove, which will warm up at a higher rate – the aluminum pot or the water? Hint: Consider the definition of specific heat capacity.

A The aluminum pot

B. The water

C. They will warm at the same rate.


QUESTION 4
Which will require more energy input to warm by 10 °C, a swimming pool full of water or a lake full of water? Hint: Consider the definition of specific heat capacity.

A swimming pool full of water

B. A lake full of water

C. They will require the same energy input.

Answer:

Q3 the right answer is  A) the aluminium pot

QUESTION 4   B. A lake full of water ( also depends on volume and mass of water)

Explanation:

Q3. the specific heat capacity is the amount of heat one gram of substance absorb or release to change temperature by one degree centigrade.

The aluminum  heats faster than the water because it requires less energy to heat it up.

but its also have the radiates/conducts away all of its heat so rapidly that it cools off much faster than anything else.

Q4.

If a swimming pool and lake full of water, both full of water at the same temperature were subjected to the same input of heat energy, the lake  would certainly rise in temperature more quickly than the swimming pool. The heat capacity of an object depends both on its mass and its chemical composition. Because of its much larger mass, the lake full  of water has a larger heat capacity than the swimming pool full of water.
