Explain why Pyrex®, a glass with a small coefficient at lineal expansion, is less susceptible.arrow_forwardIntegrated Concepts Heat transfers from your lungs and breathing passages by evaporating water. (a) Calculate the maximum number of grams of water that can be evaporated when you inhale 1.50 L of 37C air with an original relative humidity of 40.0%. (Assume that body temperature is also 37C .) (b) How many joules of energy are required to evaporate this amount?

- The “steam” above a freshly made cup of instant coffee is really water vapor droplets condensing after evaporating from the hot coffee. What is the final temperature of 250 g of hot coffee initially at 90.0C if 2.00 g evaporates from it? The coffee is in a Styrofoam clip, so other methods of heat transfer can be neglected.arrow_forwardThe temperature of a silver bar rises by 10.0C when it absorbs 1.23 kJ of energy by heat.

What is the rate of heat transfer out of Earth by convection if this lava has a density of 2700kg/m3 and eventually cools to 30C ? Assume that the specific heat of lava is the same as that of granite. Figure 14.34 Lava flow on Kilauea volcano in Hawaii. (credit: J. R Eaton, U.S. Geological Survey)arrow_forward
- Does it really help to run hot water over a tight metal lid on a glass jar before flying to open it? Explain your answer.arrow_forwardIn some countries, liquid nitrogen is used on dairy trucks instead of mechanical refrigerators. A 3.00-hour delivery trip requires 200 L of liquid nitrogen, which has a density at 808kg/m3. (a) Calculate the heat transfer necessary to evaporate this amount of liquid nitrogen and raise its temperature to 300C. (Use cp and assume it is constant over the temperature range.) This value is the amount of cooling the liquid nitrogen supplies. (b) What is this heat transfer rate in kilowatthours? (c) Compare the amount of cooling obtained from melting an identical mass at 0C ice with that from evaporating the liquid nitrogen.arrow_forwardConstruct Your Own Problem Consider a new model of commercial airplane having its brakes tested as a part of the initial flight permission procedure. The airplane is brought to takeoff speed and then stopped with the brakes alone. Construct a problem in which you calculate the temperature increase of the brakes during this process. You may assume most of the kinetic energy of the airplane is converted to thermal energy in the brakes and surrounding materials, and that little escapes. Note that the brakes are expected to become so hot in this procedure that they ignite and, in order to pass the test, the airplane must be able to withstand the fire for some time without a general conflagration.arrow_forward
- Water expands significantly when it freezes: a volume increase at about 9% occurs. As a result of this expansion and because of the formation and growth of crystals as water freezes anywhere from 10% to 30% of biological cells are burst when animal or plant material is frozen. Discuss the implications of this cell damage for the prospect of preserving human bodies by freezing so that they can he thawed at some future date when it is hoped that all diseases are curable.arrow_forward€69.
