Question 1

An 8 000-kg aluminum flagpole 100-m long is heated by the sun from a temperature of 10°C to 20°C. Find the heat transferred (in J) to the aluminum if the specific heat of aluminum is 0.215 cal/g⋅°C.

Question 2

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. Sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. Which one, if either is correct?

◦
Beryl, because low thermal conductivity results in low heat transfer.

◦
Beryl, because low thermal conductivity results in high heat transfer.

◦
Sapphire, because low thermal conductivity results in low heat transfer.

◦
Sapphire, because low thermal conductivity results in high heat transfer.

◦
Neither, because low heat transfer is desirable both in summer and in winter.
