An ideal gas initially at P,, V, and T, is taken through a cycle ABCDA as shown in Figure 5. Determine in terms of P, and V, the net work done on the gas per cycle. the change in the system internal energy. the net energy added by heat to the system per cycle. 3P1 P, D. V, 3V,
For the heat resistance of a material, it must be made in a certain thickness. In other words, as the temperature to be tolerated increases, the required thickness increases. This increase has two components. Exponential and linear. You can assume the coefficient of the exponential part as one, keeping only the parameter in exponential variable. Using the temperature and thickness values given below, find out how much thịckness is reguired for 100 degrees. Нeat Thickness 50 200 50 60 250

1. We have 500 in³ of nitrogen at 1640 psi gauge pressure at 85°F. What is the volume at 1250 psi gauge pressure at 40°F? Show working equation with answer. Answer must be in in^3.
State the units in which the characteristic gas constant R is usually expressed 3. and explain why it has not the same value for all gases. In an experiment to determine specific heat capacity of the air at constant pressure, 50 g of air at constant pressure were heated from 14°C to 74 °C during the period 300 seconds by continuous electric heating method. The average value of the power used by heater was 10.04 Watts. Use the information to find the value of the specific heat capacity of air at constant pressure. Hence find a- the value of the characteristic gas constant R b-the density of the air at 0°C and 0.1 MPa. y =1.4
