You have been given 1.326071 g of copper from which you are to fashion a wire whose resistance is 2.2619253 ohms. the density of copper is 8900 kg/m 3 and the resisitivity of copper is 1.7 x 10^-8 ohm m. what will the diameter of the wire be that you fashion?

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
