How much work must be done on the gas to reduce the volume by 60% in a constant temperature process?You are building a container out of polystyrene to hold a liquid at 80 °C.The surface area of this container is 1.2 m2.a. If energy is being added at a rate of 50 J/s (that is, 50 W), how thick mustthe container be to keep the outside temperature below 30 °C?b. What would be the required thickness if the container were instead madeout of nickel?A cylindrical glass flask with a diameter of 8 cm and the height of 20 cm is fully filled with water at 20°C. When the temperature of the water (and consequently the inner surface of the flask) is raised to 100° C, determine the volume of the water that overflows? HINT 1: Don't forget to calculate the initial volume of the water and flask HINT 2: The volume expansion coefficient for ordinary glass and water can be found in the table of Week 4 (Slide #20). HINT 3: Calculate the volume expansions for both water and the flask HINT 4: The difference between the final volume of water and the final volume of the flask is the amount of overflow.
