Click on photo for a larger picture. In the photo above, I am holding two small vials of liquid metal. The vial on the right contains gallium, an element that melts at 29.76Â° Celsius (85.57Â° Fahrenheit). The vial on the left is an alloy that contains gallium, indium, and tin, and melts at -20Â° Celsius (-4Â° Fahrenheit). The gallium is liquid because I had the bottle in my shirt pocket, next to my warm body.
6. Silver melts at 962 degrees Celsius and boils at 2,210 degrees Celsius; Gold melts at 1,064 degrees Celsius and boils at 2,900 degrees Celsius. 7. Temperatures in our universe range from about 3,500,000,000 Kelvin (a supernova) to about 3 Kelvin (space). Our Sun is a class G yellow star and has an average surface temperature of 5,600 Kelvin. 8.
