Question

Room temperature is commonly regarded as 68.0 °f. gallium has a melting point of 29.8 °c. what is the difference between the melting point and the temperature of the surroundings (68 °f)?

Answer 1

The difference in the temperatures between the room temperature and the melting point of Gallium is 9.8°C.

Express the room temperature of 68°F in °C.

`C=(5)/(9)  (F-32)\\   =(5)/(9) (68-32)\\  = 20^o C`

Find the difference between the melting point of Gallium and the room temperature.

`\Delta T = (29.8^oC - 20^oC)\\  =9.8 ^oC`

The difference between the room temperature and the melting point of Gallium is 9.8 °C.
