Three liquids are at temperatures of 12°C, 19°C, and 35°C, respectively. Equal masses of the first two liquids are mixed, and the equilibrium temperature is 16°C. Equal masses of the second and third are then mixed, and the equilibrium temperature is 27°C. Find the equilibrium temperature when equal masses of the first and third are mixed.

⦁   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...

Equal masses of two different liquids have the same temperature of 22.1 °C. Liquid A has a freezing point of -63.0 °C and a specific heat capacity of 1790 J/(kg C°). Liquid B has a freezing point of -82.9 °C and a specific heat capacity of 2580 J/(kg C°). The same amount of heat must be removed from each liquid in order to freeze it into a solid at its respective freezing point. Determine the difference Lf,A - Lf,B between...

Three thermally insulated containers of equal volume are connected together by thin tubes of negligible volume so that gas can flow from one container to the next when a valve between them is open. Initially, the pressure and temperature in each container is at the same value Po and To, respectively. The valves between the vessels are opened, and thermal insulation is removed from two of the vessels. Then two vessels are surrounded by heat reservoirs so that their temperatures...

You have two containers of the same liquid. The first container has 142.0 g at T1°C and the second has 25 g at 21°C. In order to consolidate and save space, you mix the two liquids into one container and find that the two portions have now reached an equilibrium temperature of 42.6°C. What was the initial temperature of the liquid in the first container? °C

A warehouse employs 26 workers on first​ shift, 19 workers on second​ shift, and 10 workers on third shift. Eight workers are chosen at random to be interviewed about the work environment. Find the probability of choosing exactly two second shift workers and two third shift workers. The probability of choosing two second shift workers and two third shift workers is nothing. ​(Round to three decimal places as​ needed.)
