Katy Perry

Katheryn Elizabeth "Katy" Hudson (born October 25, 1984), known professionally as Katy Perry, is an American singer, songwriter, and actress. After singing in church during her childhood, she pursued a career in gospel music as a teenager. Perry signed with Red Hill Records and released her debut studio album Katy Hudson in 2001, which was commercially unsuccessful. She moved to Los Angeles the following year to venture into secular music after Red Hill ceased operations. After being dropped by The Island Def Jam Music Group and Columbia Records, Perry signed a recording contract with Capitol Records in April 2007.

Perry rose to fame in 2008 with the release of the singles "I Kissed a Girl" – which sparked controversy for its homosexual themes – and "Hot n Cold" from her second album, a pop rock record titled One of the Boys. Her third album, Teenage Dream (2010), ventured into disco, and contained the U.S. Billboard Hot 100 chart-topping singles "California Gurls", "Teenage Dream", "Firework", "E.T.", and "Last Friday Night (T.G.I.F.)" as well as the number-three single "The One That Got Away". The album became the first by a female artist to produce five number-one Billboard Hot 100 songs, and the second overall after Michael Jackson's album Bad. In March 2012, she reissued the album as Teenage Dream: The Complete Confection, which produced the songs "Part of Me" and "Wide Awake".

Hot n Cold

"Hot n Cold" is a song by American singer Katy Perry. The song was written by Perry, Dr. Luke and Max Martin and produced by Dr. Luke and Benny Blanco for her second studio album, One of the Boys (2008). The track was released as the album's second single on September 9, 2008. The lyrics address an unstable romantic relationship caused by a partner's mood swings.

The song received mixed to positive reviews from music critics. It reached number three on the Billboard Hot 100, becoming Perry's second consecutive top three single, after her previous hit "I Kissed a Girl". It also became Perry's second top five single in the United Kingdom, Australia, Ireland and New Zealand, and topped the charts in Finland, Germany, Canada, Norway, Spain and Denmark, among others. To date, "Hot n Cold" has sold over six million digital downloads worldwide, making it one of the best-selling singles worldwide and one of Perry's highest-selling singles to date.

To promote "Hot n Cold", Perry marked the song's live debut with a performance on NBC's Today. She also performed the song at the 2008 MTV Europe Music Awards, which she hosted. The song's music video, which was directed by Alan Ferguson, was released on October 1, 2008 and features Perry as a bride who is about to get married to her fiancé, who experiences a daydream in which she pursues him after he flees from the church. "Hot n Cold" was nominated for the Grammy Award for Best Female Pop Vocal Performance at the 52nd Annual Grammy Awards. Perry also performed the song on the Hello Katy Tour, California Dreams Tour, and Prismatic World Tour.

How cold

When I woke up this morning
it was very cold.
How cold was it?
It was a freezing, sneezing
goose-bumpy, teeth-chattering,
can't-get-out-of-bed,
blankets-over-my-head
kind of cold

Cold refers to the condition or subjective perception of having low temperature, the absence of heat.

A lower bound to temperature is absolute zero, defined as 0 K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to −273.15 °C on the Celsius scale, −459.67 °F on the Fahrenheit scale, and 0 °R on the Rankine scale.

Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in this classical sense. The object would be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because of the uncertainty principle.
