In a closed flask of 5 L, 1.0 g of $H_2$ is heated from 300 to 600 K. Which statement is not correct?
Updated On: Apr 10, 2024
- Pressure of the gas increases
- The rate of collision increases
- The number of moles of gas increases
- The energy of gaseous molecules increases

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The correct option is(C): The number of moles of gas increases.
Here, volume is constant and mass of hydrogen gas is also fixed, therefore the number of moles remains same. Now as the temperature increases, then pressure also increases. This will lead to more collisions among the gaseous molecules and hence, the energy of molecules increases.

States of Matter
The matter is made up of very tiny particles and these particles are so small that we cannot see them with naked eyes.
There are three States of Matter:
The three states of matter are as follows:
Solid State:
- The solid-state is one of the fundamental states of matter.
- Solids differ from liquids and gases by the characteristic of rigidity.
- The molecules of solids are tightly packed because of strong intermolecular forces; they only oscillate about their mean positions.
Liquid State:
- The molecules in a liquid are closely packed due to weak intermolecular forces.
- These forces are weaker than solids but stronger than that of gases.
- There is much space in between the molecules of liquids which makes their flowing ability easy.
Gaseous State:
- In this state of matter, distances between the molecules are large (intermolecular distance is in the range of 10-7-10-5 cm.
- The intermolecular forces experienced between them are negligible.
- Thus, translatory, rotatory and vibratory motions are observed prominently in gases.
