large slab of concrete,

1. A large slab of concrete, 5 × 8 × 0.3 m, is used as a thermal storage mass in a solar-heated house. If the slab cools overnight from 23◦C to 18◦C in an 18◦C house, what is the net entropy change associated with this process?

2. A foundry form box with 25 kg of 200â—¦C hot sand is dumped into a bucket with 50 L water at 15â—¦C. Assuming no heat transfer with the surroundings and no boiling away of liquid water, calculate the net entropy change for the mass.
