Description | Before we define what relative humidity is, we need to understand the concept of partial pressure. Our atmosphere is composed of many different types of gas molecules including but not limited to nitrogen, oxygen, water vapor and carbon dioxide. Each one of these types of gases creates its own pressure within the atmosphere. This pressure that each type of gas creates is known as partial pressure and if we add up all the partial pressures of all the gas molecule types, we would obtain the total pressure within the atmosphere. The atmosphere, just like a sponge can only hold so many particular gas molecules until it becomes completely saturated. After it reaches this saturation point, it can no longer hold that type of molecule. We define relative humidity as the ratio of the partial pressure of water vapor to the saturated water vapor pressure multiplied by 100 %. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
