7800° Fahrenheit

7800° Fahrenheit is the second studio album by American rock band Bon Jovi. It was released on March 27, 1985, through Mercury Records. The album's title is a reference to the supposed melting point of rock, which is equivalent to 4315.5 °C. In the United States, the Fahrenheit scale is in general use, suggesting the album consists of "American hot rock". The album's artwork introduced the classic 1980s Bon Jovi logo that would later be used on Slippery When Wet and New Jersey. 7800° Fahrenheit spent 104 weeks on the Billboard 200 albums chart and was certified platinum by the Recording Industry Association of America (RIAA) on February 19, 1987. The singles "Only Lonely" and "In and Out of Love" both charted on the Billboard Hot 100.
