Q.n.1) A moon of Jupiter, possesses volcanoes that emit molten sulfur. Consider 1 metric ton of solid sulfur at a temperature of 00C. How much energy must the sulfur absorb to become molten sulfur at a temperature of 3500C? Use specific heats of 705 J/(kg K) and 406 J/(kg K) for solid and molten sulfur respectively. Other information needed is tabulated in text.
Explanation / Answer
Since the sulfur is in solid state and its temperature is 00 C therefore first we have to know that what is the melting point of sulfur. The melting point of sulfur is approx 115.20 C therefore the energy required by the sulfur to reach this temperature from 0 C will be
Q1 = mCdT -----(1) where m is mass i.e. 1 ton , C is specific heat of solid sulfur i.e. 705 J/kg K and dT is change in temperature.
Now we have to know about the latent heat for sulfur assume that H so the energy will be
Q2 = mH ---(2)
Now the energy is require to raise the temperature of the sulfur from 115.20 C to the temperature of 35000C so again Q3 = mC2 dT where C2 is the specific heat of molten sulfur and dT is the change in temperature.
Now we will add up all the three energy which will give us the total energy require to convert the solid sulfur of 00C to the molten sulfur of 35000C.
