Which of the following is true? The final temperature of the coffee cup will be less than 20°C. The final temperature of the coffee cup will be 80°C. The final temperature of the coffee cup will be more than 80°C The final temperature of the coffee cup will higher than 25°C but less than 70°C. Question 14 (1 point) Which of the following has a standard enthalpy of formation of zero?

Answer 1

As we know temperature is an intensive property. By mixing two substances at different temperatures we cannot take mean of the two different temperatures.

Buly knowing the Cp values of metal and water we can calculate final temperature of the system. And final temperature range will be in between the lower and higher value.
