Two square wires are composed differently, see the figure of their cross-sections. Wire 1 is a square wire of material A but with a circular center of material C. The diameter of the circular inside is equal to the length of side of the square. The second square wire has the same cross-sectional area as the first but is entirely comprised of material A. Both wires are the same length and setup to have the same temperature difference maintained between...

PLEASE ANSWER a,b,c
Heat Conduction Heat conduction occurs through any material, represented here by a rectangular bar, whether window glass or walrus blubber. The temperature of the material is T2 on the left and T1 on the right, where T2 is greater than T1. The rate of heat transfer by conduction is directly proportional to the surface area A, the temperature difference T2 - T1, and the substance's conductivity k. The rate of heat transfer is inversely proportional to the...

1) Calculate the heat through a glass window that is 30.0 cm*150 cm in area and 1.20 mm&n
1) Calculate the heat through a glass window that is 30.0 cm*150 cm in area and 1.20 mm thick. Assume the temperature onthe inside of the window is 25.0�C while the outside temperature is 8.00�C. 2)Five hundred joules of heat is absorbed by a system that does 200 J of work on its surroundings. What is the change in the internal energy of the system? 3)An ideal gas expands isothermally, performing 8.80 kJ of work in the process. Calculate the heat absorbed during the expansion. 4)A gas contained in a cylinder that has a piston is kept at a constant pressure of 2.80*10^5Pa. The gas expands from0.500 m^3to 1.50 m^3 when 300 kJ...

Temperature Change and Heat Capacity - Calorimetry- Two substances The quantitative relationship between heat transfer and temperature change is Q = mcAT, where Q is heat transfer, m is the mass of the substance, and AT is the change in temperature. The symbol c stands for specific heat and depends on the material and phase. The specific heat c is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00°C....

can you write a conclusion for the report? Thermal Conductivity Lab Introduction The objective of this lab is to explore the thermal conductivity of various materials using Fourier’s Law and a steady state system. Certain materials are more effective heat conductors than others. The effectiveness of a given material at heat conduction is influenced by many factors, including density, molecular structure, and chemical composition. Fourier’s Law takes these factors into account to calculate Q, or the joules per second rate...
