Energy tranfer takes place either by means of Heat or Work only in Thermodynamics.

Heat :: Heat Energy is defined as Energy that can be transferred due to temperature change.

Whereas

Thermal Energy :: Thermal Energy is the Internal Energy stored in the system maintained at a certain Temperature.

He cannot issue an ordinance , when both the Houses of Parliament are in session. Every ordinance issued by the President should be laid before both Houses of Parliament, within six weeks of re-assembly of Parliament . The president may also withdraw an ordinance at any time he likes.

The most important polymer present in the nucleus is DNA- the master molecule. It is a polymer of Nucleotides.

In thermodynamics, deposition is a phase transition in which gases are directly transformed to solids without converting to liquids first.

For example, watervapour is directly changed to ice without first becoming to liquid water. In this process, heat is released making the process exothermic process.

A Disease which spreads by contact are Contagious.

Infectious diseases : These are caused by microscopic germs such as bacteria or viruses that get into the body and cause problems. Some but not all infectious diseases spread directly from one person to another. Infectious diseases that spread from person to person are said to be contagious. Some infections spread to people from an animal or insect, but are not contagious from another human. 

Contagious diseases such as the flu, colds, or strep throat spread from person to person in several ways. One way is through direct physical contact, like touching or kissing a person who has the infection. Another way is when an infectious microbe travels through the air after someone nearby sneezes or coughs.

Fatal Diseases : Diseases leading to failure or disaster.

Incurable Diseases : Diseases of a sick person not able to be cured.

Convection is the mode of heat transfer which involves bulk motion of a fluid to transfer heat. Energy transfer by convection is primarily restricted to fluids. Fluids can be both liquids and gases.

The study of statistics such as births, deaths, income, or the incidence of disease, which illustrate the changing structure of human populations.

In brief, Study of both quantitative and qualitative aspects of human population.

1. Quantitative aspects include composition, density, distribution, growth, movement, size, and structure of the population.

2. Qualitative aspects are the sociological factors such as education quality, crime, diet, development, nutrition, wealth and well being.
