                            For the T-V curves of an ideal gas at pressures \(P_1, P_2, P_3\) compared to Charles’s law (dotted lines), the correct relation is:                        
                                                
                                                
                                                
                        
                                                                                                
                                                                                                                                
                                                                                                                                
                                                                                                                                
                                                                                                                                                
                        
                        
                        
                        
                            
                                
                                Correct Answer: 
                                D
                            
                                                            
                                    
                                    
                                        Explanation: 
                                        Higher pressure curves deviate more from Charles’s law (ideal low-pressure behavior).
