Determine how much the melting point of naphthalene is higher than the melting point of mercury
| June 22, 2021 | education
The melting point of naphthalene is 80.26 ° C.
The melting point of mercury is -38.8 ° C.
The temperatures indicated must be expressed in degrees Kelvin:
Tn = 80.26 ° C + 273 = 333.26 K;
Tr = -38.8 ° C + 273 = 234.2 K;
Tn – Tr = 333.2 K – 234.2 K = 99 K.
Answer. The melting point of naphthalene is 99 ° C (or 99 K) higher.
