A bimetallic strip of total thickness "x" is straight at temperature T. what is the radius of curvature of the strip, R, when it is heated temperature T+AT?. The coefficients of linear expansion of the two metals are ai > a. You may assume that each metal has thickness x/2, and you may assume that x
Kinetic Theory of Gas
The Kinetic Theory of gases is a classical model of gases, according to which gases are composed of molecules/particles that are in random motion. While undergoing this random motion, kinetic energy in molecules can assume random velocity across all directions. It also says that the constituent particles/molecules undergo elastic collision, which means that the total kinetic energy remains constant before and after the collision. The average kinetic energy of the particles also determines the pressure of the gas.
P-V Diagram
A P-V diagram is a very important tool of the branch of physics known as thermodynamics, which is used to analyze the working and hence the efficiency of thermodynamic engines. As the name suggests, it is used to measure the changes in pressure (P) and volume (V) corresponding to the thermodynamic system under study. The P-V diagram is used as an indicator diagram to control the given thermodynamic system.
Q.2) A bimetallic strip of total thickness "x" is straight at temperature T. what is the radius of curvature of the strip, R, when it is heated temperature T+AT?. The coefficients of linear expansion of the two metals are ai > a. You may assume that each metal has thickness x/2, and you may assume that x <R. [13]
Q.3) A gas within a closed chamber undergoes the cycle shown in the P-V diagram. The horizontal scale set by Vs =4.0 m². Calculate the net energy added to the system as heat during one complete cycle. [10] 40 30 Pressure (N/m) 20 P 10 Volume (m")
Q.4) Suppose 100 J of work is done on a system and 60.0 calis extracted from the system as heat in the sense of the first law of themodynamics. What are the values (including algebric signs) of (a) W, (b) Q, and (c) Internal energy
