Sue's Table
Good Conductors of Heat Bad Conductors of Heat
Silver
Cotton
Copper
Wool
Cork
Air
Why is Sue's table incorrect?
O Air is a good conductor of heat.
O Wool is a good conductor of heat.
O Cork is a bad conductor of heat.
O Copper is a bad conductor of heat.

Air is a good conductor of heat because it conducts heat

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
