Which materials should Hannah choose for her pot and spoon?
A
Hannah should choose copper for her pot because it has the lowest specific heat, and she should choose wood for her spoon because it has the highest specific heat.
B
Hannah should choose wood for her pot because it has the highest specific heat, and she should choose copper for her spoon because it has the lowest specific heat.
C
Hannah should choose wood for her pot because it has the highest specific heat, and she should choose rubber for her spoon because it has the second highest specific heat.
D
Hannah should choose copper for her pot because it has the lowest specific heat, and she should choose steel because it has the second lowest specific heat.
The correct answer is B. Hannah should choose wood for her pot because it has the highest specific heat, and she should choose copper for her spoon because it has the lowest specific heat.
B
Hannah should choose wood for her pot because it has the highest specific heat, and she should choose copper for her spoon because it has the lowest specific heat.
To determine which materials Hannah should choose for her pot and spoon, we need to consider the specific heat of each material.
Specific heat is the amount of heat energy required to raise the temperature of a unit mass of a substance by one degree Celsius. Materials with high specific heat can absorb more heat energy without a significant increase in temperature, while materials with low specific heat heat up quickly with less heat energy.
Looking at the options given:
Option A suggests that Hannah should choose copper for her pot because it has the lowest specific heat, and wood for her spoon because it has the highest specific heat. This is incorrect because copper has a high specific heat, not low.
Option B suggests that Hannah should choose wood for her pot because it has the highest specific heat, and copper for her spoon because it has the lowest specific heat. This is incorrect because wood has a low specific heat, not high.
Option C suggests that Hannah should choose wood for her pot because it has the highest specific heat, and rubber for her spoon because it has the second highest specific heat. This option is incorrect because rubber does not have a particularly high specific heat.
Option D suggests that Hannah should choose copper for her pot because it has the lowest specific heat, and steel because it has the second lowest specific heat. This is a correct answer because copper has a lower specific heat compared to other materials, and steel has a relatively low specific heat.
Therefore, the correct answer is D: Hannah should choose copper for her pot because it has the lowest specific heat, and she should choose steel for her spoon because it has the second lowest specific heat.
