Re: H2O



A college physics student asks the following question:


How can water be both a good thermal insulator and a good electrical
conductor?

How would the list answer this?

at the ever constant risk of sounding like an idiot: is this a trick
question? 1) thermal insulation properties have more to do with specific
heat of a substance, and 2) water is a very poor electrical conductor
unless it has lots of foreign ions present.
