The lighting fixtures used are 1x22-Watt LED (The lumens output of each LED lamp is 3000 lumens). The Utilization factor was found to be 0.55. What is the area of the Auditorium library? Assume a reduction factor of 1 and a depreciation factor of 1.5. Select one: 1100 m² O O 275 m² 40900 m² 550 m²The pressure, P of an ideal gas, can be expressed as P = nRT/V where n is the number of moles, T is the temperature, V is the volume and R = 8.314JK^-1 mol^-1 is the ideal gas constant. a) Find the expression for deltaP in terms of deltan, deltaT and deltaV: deltaP = deltan + deltaT + deltaV b) Suppose that n = 1, V = 1m^3 and T = 300K initially. If n and V change to 9/5 and 7/10m^3 respectively, estimate the change in T(K) required to keep P constant.
