The metal rhenium becomes superconducting at temperatures below 1.4 K. Calculate the temperature at which rhenium becomes superconducting in degrees Celsius.

The temperature at which rhenium becomes superconducting is -271.6 ºC.

Explanation:

We can convert the temperature given in Kelvin, which is an absolute scale, into degrees Celsius. which is a relative scale, by a simple algebraic translation, that is:

(1)

Where:

- Temperature, measured in degrees Celsius.

- Temperature, measured in Kelvins.

If we know that , then the temperature given in degrees Celsius is:

The temperature at which rhenium becomes superconducting is -271.6 ºC.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
