- One mole of oxygen gas is at a pressure of 6.40 atm and a temperature of 31.5°C. (a) If the gas is heated at constant volume until the pressure triples, what is the final temperature? °C(b) If the gas is heated so that both the pressure and volume are doubled, what is the final temperature?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. PLEASE UPLOAD YOUR HANDWRITTEN SOLUTION BY CLICKING ON THE "ADD A FILE" BUTTON.You happen to come across a piece of metal that has a density of p 8.12 g/cm3 when the temperature is To = 42.5 °C. If the metal is cooled to a temperature of T1 0.00 °C, does the density change? Yes, the density will decrease since the volume changes. Yes, since the metal contracts and the mass is constant, the density will increase. No, because as the volume changes so does the mass. No, density does not depend on temperature. Calculate the density of the piece of metal at this temperature, P1. The coefficient of volume expansion for this piece of metal is B = 7.62 x 10-5 1/°C. -0.0263 Pi = g/cm3 Incorrect
- At 19.5°C, the radius of a solid aluminum sphere is 8.00 cm. (a) At what temperature will the volume of the sphere have increased by 2.50%? °C (b) What is the increase in the sphere's radius if it is heated to 300°C? Assume a = 22.2 x 10-6 K-1 and B = 66.6 × 10-6 K-1. 5 x cmA steel rod 30.0 m long, installed when the temperature was 10°C, is in a bridge that heats up to 40oC on a hot summer day. Steel's coefficient of linear expansion is 1.2 × 10-5 K-1. The bridge is built so the rod has an expansion space of 5 cm. Is this enough space? What is the increase in the length of the rod, in mm?A Styrofoam box has a surface area of 0.80 m and a wall thickness of 2.0 cm. The temperature of the inner surface is 5.0°C, and the outside temperature is 25°C. If it takes 8.0 h for 5.0 kg of ice to melt in the container, determine the thermal conductivity of the Styrofoam.
