Answer the following questions:

A rod with a length of 1.5 m is made of copper, which has a coefcient of linear expansion of 1.70 x 10'5 (C)'1. It is initially at a temperature of 31C. (a) What is the change in length of the rod if the temperature drops to 0.0C? (Give the absolute value in units of mm.) Em (b) How does the rod's length change with lower temperature? 0 The rod shrinks with lower temperature. 0 The rod expands with lower temperature. 0 The rod's length does not change with lower temperature. (c) Find the absolute value of the fraction by which the rods length changes between the two temperatures. =l:l L 0 A student drops an ice cube into an insulated container full of water and waits for the ice cube to completely melt. The ice cube initially has a mass of 105 g and a temperature of 0C. The water (before the ice cube is added) has a mass of 1.00 kg and an initial temperature of 90C. What is the final temperature (in C) of the mixture? (Assume no energy is lost to the walls of the container, or to the environment.) |:lC You place frozen soup (T = 11C) in a microwave oven for 3.7 min. The oven transfers 640 W to the soup. Model the soup as 0.35 kg of water (initially ice). What is the temperature of the soup when the oven stops? |:] C What is the state of the soup when the oven stops? 0 gas 0 plasma 0 solid 0 liquid A gas occupies a volume of 12.8 L at a pressure of 33.0 mm Hg. What is volume when pressure is increased to 53.0 mm Hg? |:]L A gas has a volume of 755 mL at -18C and 250 torr. What would be the new volume if the temperature is increased to 257C and the pressure increased to 520 torr? Em
