I want old question papers with solutions of the IIT JEE exam because I am going to apply for the exam and have no idea about the pattern of the exam. So please give me the paper or any website from where I can get the papers.

You are looking for the old question paper of the IIT JEE
So I have listed some question here and if you want more question related to IIT JEE then open PDF file.

Q. 1 Let X be the energy needed to raise the temperature of 5 moles of nitrogen held at constant pressure by one degree. Let Y be the energy needed to raise 5 moles of carbon monoxide by one degree with the pressure held constant. What is the ratio X:Y?

5:7
1:1
7:5
7:9

Discription: There is no need to do any calculations here. If you put X on top of Y, you will see that it reduces to the ratio of Cp for nitrogen over Cp for carbon monoxide. And since both gases have the same Cp, the ratio is simply 1:1.

Q. 2 The difference Cp - Cv is a constant. This constant is often called R, the universal gas constant. Which of the following is true given the data?

For a monoatomic gas, Cp = 3/2 R
For a diatomic gas, Cp = 3/2 R
For a monoatomic gas, Cv = 3/2 R
For a diatomic gas, Cv = 3/2 R

Discription: Helium and argon are monoatomic gases, and we can see that Cv = 3/2 *R = (3/2)*2 = 3.

Q. 3 How much energy would be required to heat two moles of methane by one degree if the gas is kept at constant volume?

6.5 calories
8.5 calories
11 calories
13 calories

Description: The definition of Cv is the amount of energy required to heat one mole of a gas by one degree. Therefore, to heat two moles of methane by one degree will require 2*6.5 = 13 calories.

Q. 4 Which of the following is a possible explanation for the fact that Cp is always greater than Cv?

Some of the energy is used to expand the container in order to maintain constant pressure.
A rigid container does not conduct heat as well as one that can change shape.
There are generally more moles of gas when the pressure is kept constant than when the volume is kept constant.
There are generally fewer moles of gas when the pressure is kept constant than when the volume is kep constant.

Discription: Because Cp is always greater than Cv we know that it takes more energy to increase a given amount of gas when the pressure is held constant. It is reasonable that the extra energy is used to increase the volume of the container.

Q. 5 A certain amount of energy, X, is sufficient to raise the temperature of 60 moles of argon by T degrees when the pressure is constant. How many moles of argon can be raised by T degrees with the same amount of energy X, if the volume is held constant?

30
50
75
100
