When eating a piece of hot apple pie, you may find that the crust is only warm but the apple filling burns your mouth. Why?
Broiling is a method of cooking by radiation, which produces somewhat different results from cooking by conduction or convection. A gas flame or electric heating element produces a very high temperature close to the food and above it. is radiation the dominant heat-transfer method in this situation?
A box with a total surface area of 1.20 m2 and a wall thickness of 4.00 cm is made of an insulating material. A 10.0-W electric heater inside the box maintains the inside temperature at 15.0C above the outside temperature. Find the thermal conductivity k of the insulating material.
A sealed cubical container 20.0 cm on a side contains three times Avogadros number of molecules at a temperature of 20.0C. Find the force exerted by the gas on one of the walls of the container.
The air inside a hot-air balloon has a temperature of 370 K and a pressure of 101.3 kPa, the same as that of the air outside. Using the composition of air as 78% N2, 21% O2, and 1% Ar, find the density of the air inside the balloon.
When a bimetallic strip is heated, it bends away from the metal with the ___ thermal expansion. (5.1)
What does the specific heat of a substance tell you when you compare it with the specific heat of another substance?
A steam pipe is covered with 1.50-cm-thick insulating material of thermal conductivity 0.200 cal/cm C s. How much energy is lost every second when the steam is at 200.C and the surrounding air is at 20.0C? The pipe has a circumference of 800. cm and a length of 50.0 m. Neglect losses through the ends of the pipe.
Calculate the number of moles in me 2.00L volume of air in the lungs of me average person. Note that me air is at 37.0C (body temperature).
Steam at 100.C is added to ice at 0C. (a) Find the amount of ice melted and the final temperature when the mass of steam is 10. g and the mass of ice is 50. g. (b) Repeat with steam of mass 1.0 g and ice of mass 50. g.
Ethyl alcohol has about one-half the specific heat of water. Assume equal amounts of energy are transferred by heat into equal-mass liquid samples of alcohol and water in separate insulated containers. The water rises in temperature by 25C. How much will the alcohol rise in temperature? (a) It will rise by 12C. (b) It will rise by 25C. (c) It will rise by 50C. (d) It depends on the rate of energy transfer. (e) It will not rise in temperature.
The tungsten filament of a certain 100-W lightbulb radiates 2.00 W of light. (The other 98 W is carried away by convection and conduction.) The filament has a surface area of 0.250 mm2 and an emissivity of 0.950. Find the filaments temperature. (The melting point of tungsten is 3 683 K.)
