Gallium is a solid metal at room temperature, but it will melt to a liquid
Gallium is a solid metal at room temperature, but it will melt to a liquid in your hand. The melting point of gallium is 85.6 °F. What is this temperature on (a) the Celsius scale and (b) the Kelvin scale?
There are three temperature scales used today, Fahrenheit, Celsius, and Kelvin.
Fahrenheit = F°= (C° x 1.8) +32
Celsius = C°= (F°- 32) / 1.8
Kelvin = K = C° + 273.15
The melting point of gallium is 85.6 °F. To convert from C° to F°, we find the equation that relates these two quantities. The temperature in C° is calculated with formula C°= (F°- 32) / 1.8. With this formula, the temperature on the Celsius scale is 29.8 C°. The temperature in C° will help us find the temperature in K. Since we have the temperature in Celsius, and we are trying to find the temperature in Kelvin, we will need to use the Kelvin equation K = C° + 273.15. We substitute the Celsius temperature 29.8 C° in the equation which makes the temperature on the Kelvin scale 302.9 K°.
