Question

1. the element silver melts at 960.8°c and boils at 2212°c. express these temperatures in kelvins.

Explanation:

Step1: Recall temperature conversion formula

The formula to convert Celsius to Kelvin is $K = ^{\circ}C+ 273.15$.

Step2: Convert melting - point temperature

For the melting - point of silver ($T_{m}=960.8^{\circ}C$), we substitute into the formula: $T_{m,K}=960.8 + 273.15=1233.95$ K.

Step3: Convert boiling - point temperature

For the boiling - point of silver ($T_{b}=2212^{\circ}C$), we substitute into the formula: $T_{b,K}=2212+ 273.15 = 2485.15$ K.

Answer:

The melting - point of silver is $1233.95$ K and the boiling - point is $2485.15$ K.
