Question

A gas contained in a cylinder surrounded
by a thick layer of insulating material is
quickly compressed. (a) Has there been
a transfer of heat? (b) Has work been
done?​

Answer 1

Answer:

(a) No.

(b) Yes.

Explanation:

(a) There's no any transfer of heat energy, as the cylindrical vessel is surrounded by an insulating material, which doesn't allow heat transfer.

(b) Work is always done when a gas is compressed by any external agent, no matter what type of system is there.
