A circular ring of iron has a tight- fitting iron bar across its diameter, as illustrated in Fig. 10.21. If the arrangement is heated in an oven to a high temperature, will the circular ring be distorted? What if the bar is made of aluminum?
Answer to relevant QuestionsEqual volumes of helium gas (He) and neon gas (Ne) at the same temperature ( and pressure) are on opposite sides of a porous membrane (Fig. 10.22). Describe what happens after a period of time, and why. There is one temperature at which the Celsius and Fahrenheit scales have the same reading. (a) To find that temperature, would you set (1) STF = 9TC (2) 9T+ = 5TC or (3) TF = TC Why? (b) Find the temperature. When lightning strikes, it can heat the air around it to more than 30 000 K, five times the surface temperature of the Sun. (a) What is this temperature on the Fahrenheit and Celsius scales? (b) The temperature is ...Is there a temperature that has the same numerical value on the Kelvin and the Fahrenheit scales? Justify your answer. The pressure on a low-density gas in a cylinder is kept constant as its temperature is increased. (a) Does the volume of the gas (1) increase, (2) decrease, or (3) remain the same? Why? (b) If the temperature is increased ...
