Two hundred grams of liquid A is at a temperature of 100◦C. One hundred grams of liquid B is at a temperature of 0◦C. When the two liquids are mixed, the final temperature is 50◦C. Which material has a higher specific heat? 1. The specific heat of A is greater than that of B. 2. The specific heat cannot be defined when fluids are mixed in this way. 3. The specific heat of A is great than B if its viscosity is greater. 4. The specific heat of B is greater than that of A. 5. The specific heats of A and B are equal.

⦁   Two identical containers A and B, filled with equal masses of 2 different liquids, initially at 20°C, are heated on a hot plate and both receive the same amount of heat. As a result, the temperature of liquid A is raised to 40°C and that of liquid B is raised to 80°C. If the liquids are now poured into a third, larger container and mixed, would their final temperature be lower, higher, or exactly equal to 60˚C? Explain your...
