system and surroundings
question 8.19 has to do with heating up a copper kettle in order to heat up the water inside. In this situation, is the kettle considered part of the system or the surroundings?

Since we are being asked to calculate the amount of heat that must be added to the kettle (containing water), I would consider it as part of the system, the whole system being kettle+water

I agree with Michelle, since we are supplying heat to a copper kettle, we are adding heat to our system, not to our surroundings. I don't think it counts as a system, but rather the boundary of the outer boundary of the system.

Re: system and surroundings
The kettle should be part of the system, which is why the kettle is included when calculating the heat that must be supplied. I guess if you think about it, the kettle must be heated first before the water can be heated.
