Heat flows through a cylindrical copper bar at the rate of 100 w. a secon bar between the same two temperatures i bar. what is the rate of heat flow through the second bar? 31. hea copper s twice as long and has twice the diameter as the first 32. the thermal conductivities of wood and concrete are 0.2 w/m k and 0.8 w/m k, pectively. suppose your house has 1-inch-thick wood siding on the outside. you would like to replace the wood siding with a concrete exterior wall. what thickness must the concrete have to provide the same insulating value as the wood? explain. 3. a titanium cube at 400 k radiates 50 w of heat. how much heat does the cube radiate if its temperature is increased to 800 k?

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).
