Why cp is always greater than cv |
| Answer» The heat capacity at\xa0constant pressure CP\xa0is\xa0greater than\xa0the heat capacity atconstant volume CV\xa0, because when heat is added at\xa0constant pressure, the substance expands and work. QV =\xa0CV\xa0△T = △U + W = △U because no work is done. Therefore, dU =\xa0CV\xa0dT and\xa0CV\xa0= dU dT . | |

What is a ribcage? |
| Answer» The rib cage is a bony and cartilaginous structure. A typical rib cage consists of 24 ribs (12 pairs), the sternum (an inverted T-shaped structure connecting the rib bones), costal cartilages and the 12 thoracic vertebrae shown in the diagram below. The first seven pairs of ribs connect directly to the sternum and are referred to as true ribs. The remaining five pairs of ribs do not connect directly to the sternum and are referred to as false ribs. The rib cage aids in the protection of the heart and lungs. | |

Kal paper hai mera chemistry ka organic ka revision notes chahiye acchi quality ke "asap" |
|
Answer» I think you have done with your exam.... Sorry.... But my suggestion will help you for your future.... Ayushi.... Here no one can provide you notes.... You can only post your question and answers can be provided to you..... As such notes can not be provided because they can be very long.... And how can anybody type so much.. So dear... You can have them on this app or from internet... Or YouTube I had also asked for Organic chemistry notes but no one gave me answer because it\'s not possible..... So I am suggesting you to take help from those apps and website... According to me...... School level notes are best available at gravity circle And for iit neet level.... Physics wallah is best for sure.... I hop you will get any help from my comment.. All the best dear ?? |

What is daltons law OF particle pressure |
| Answer» \tDalton’s law of partial pressure states that the total pressure of a mixture of ideal gases is the sum of partial pressures.\tConsider if there are several ideal gases mixed together in a vessel,then the total pressure of that vessel is equal to sum of partial pressure.\tPartial pressure is the pressure exerted by a particular gas if only that gas is present in the vessel.\tFor example: -\tConsider if in a vessel there is a mixture of 3 gases, A,B and C.So the partial pressure of A is equal to pressure exerted only by Aand considering B and C are not present.Similarly partial pressure of B is equal to the pressure exerted only by B and considering A and C are not there.Similarly for C.\t\t\tAccording to Dalton’s law the total pressure of mixture is sum of partial pressure of A, partial pressure of B and partial pressure of C. | |
