FAQs on Class 11 Chemistry Notes for All Chapters

1. What is meant by intermolecular forces?

The matter is composed of atoms and molecules, and the arrangement of these building blocks determine the shape and structure of matter. The physical properties of matter are dependent on the force of interaction between its molecules. This force is termed as an intermolecular force. The intermolecular force is highest in solids and least in gases.

2. What is the Greenhouse Effect?

The infrared radiation coming to the earth is absorbed by carbon dioxide and water vapour in the atmosphere. A part of these rays is reflected on the earth’s surface as well, causing the earth’s surface to heat up. This heating up of the earth’s surface is called global warming or the Greenhouse Effect. This phenomenon came into existence mainly due to deforestation as it increased the level of CO2 in the atmosphere. Some of the significant adverse effects of global warming are:

  • If there is a 50% increase in the air's CO2 level, the earth’s temperature goes up by 3 degrees Celsius.

  • With a 1-degree increase in the earth’s temperature, the ice caps of the polar region melt. This increases the sea level by 90 cm.

  • The rate of evaporation of water from various sources like ponds, rivers, and seas increases with temperature and causes calamities like hurricanes, cyclones, etc.
