Awell-insulated cup of water is too hot to make tea, so you mixed it with an equal amount of cool water to lower the temperature. the temperature of the mixture is exactly the midpoint between the temperature of the hot and cool water. what is the entropy change of the system consisting of the total amount of water? is it positive, negative, or no change? view available hint(s) a well-insulated cup of water is too hot to make tea, so you mixed it with an equal amount of cool water to lower the temperature. the temperature of the mixture is exactly the midpoint between the temperature of the hot and cool water. what is the entropy change of the system consisting of the total amount of water? is it positive, negative, or no change? the change in entropy of the total amount of water is positive as a result of the mixing. the sign of the entropy change cannot be determined because the amount of thermal energy transferred is not given there is no entropy change in the total amount of water as a result of the mixing. the sign of the entropy change cannot be determined because the amount of water is not given. the change in entropy of the total amount of water is negative as a result of the mixing.
