Acertain heat engine operating on a carnot cycle absorbs 370 j of heat per cycle at its hot reservoir at 145 ∘c and has a thermal efficiency of 26.0 % .

how much work does this engine do per cycle? w =

how much heat does the engine waste each cycle? |q| =

what is the temperature of the cold reservoir? tc =

by how much does the engine change the entropy of the world each cycle? deltas =

what mass of water could this engine pump per cycle from a well 25.0 m deep? m =

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? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
