Temperature is a physical property of matter that quantitatively expresses the common notions of hot and cold. Objects of low temperature are cold, while various degrees of higher temperatures are referred to as warm or hot. Heat spontaneously flows from bodies of a higher temperature to bodies of lower temperature, at a rate that increases with the temperature difference and the thermal conductivity. No heat will be exchanged between bodies of the same temperature; such bodies are said to be in "thermal equilibrium".
The temperature of a substance typically varies with the average speed of the particles that it contains, raised to the second power; that is, it is proportional to the mean kinetic energy of its constituent particles. Formally, temperature is defined as the derivative of the internal energy with respect to the entropy.
Quantitatively, temperature is measured with thermometers, which may be calibrated to a variety of temperature scales.
Temperature plays an important role in all fields of natural science, including physics, geology, chemistry, atmospheric sciences and biology.
Sean Paul Ryan Francis Henriques (born January 9, 1973), who performs under stage name Sean Paul, is a Jamaican dancehall and reggae artist.
Sean Paul was born in Kingston and spent his early years in Upper Andrew Parish, a few miles north of Kingston.

Sean Paul played for the national water polo team from the age of thirteen to twenty-one, when he gave up the sport in order to launch his musical career. He attended the Wolmers High School for Boys, Belair School, Hillel Academy High School, and the College of Arts, Science, and Technology, now known as the University of Technology, where he was trained in commerce with a view to pursuing an occupation in hotel management.
Iryn Namubiru, also known as Irene Namubiru is a female, Ugandan performing artist, resident in Paris, France.
She was born in Central Uganda. Namubiru attended several educational institutions, including:
While at Namasagali College, Iryn met another current female, Ugandan, performing artist, who was attending the college at the same time; Juliana Kanyomozi. They became friends.
According to Iryn, she has always had a passion for singing since her childhood and always strove to make this talent a bigger part of her life. Her first major attempt at success in the music industry came in 1995 when she joined singers Ragga Dee and Messe[disambiguation needed ] to release a single. Soon after wards, she had her first stage appearance in September 1995.
In 1999, she joined Juliana Kanyomozi, her former school mate at Namasagali College, and together they formed the R&B all-girl group called I-Jay. In 2000, they released their first single which got 'moderate' air play on radio stations in Uganda.
