Solved in 2 steps
- If I bring a small object at temperature 200C in thermal contact with a large object at the same temperature, a) thermal energy will flow from the large to the small object because the large object has more internal energy. b) thermal energy will flow from the small to the large object because that will increase entropy. c) thermal energy will not flow.Which would cause a more serious burn: 30 g of steam or 30 g of liquid water, both at 100 °C; and why is this so? O Water, because its specific heat is greater than that of steam. O Steam, because of its specific heat capacity. O Water, because it is denser than steam. O Steam, because of its latent heat of vaporization. O Either one would cause a burn of the same severity since they are both at the same temperature.
