🤓 Based on our data, we think this question is relevant for Professor May's class at EKU.

Four things happened to SO_{2} when it was converted from solid to gas as shown below:

When calculating heat, we will use two equations:

1. Use the following equation for the steps where SO_{2} is in the same phase and increasing temperature:

2. Use the following equation for phase changes:

**Calculate amount of heat required convert SO _{2(s)} to SO_{2(l)}:**

Sulfur dioxide is produced in enormous amounts for sulfuric acid production. It melts at −73°C and boils at −10.°C. Its Δ*H*°_{fus} is 8.619 kJ/mol, and its Δ*H*°_{vap} is 25.73 kJ/mol. The specific heat capacities of the liquid and gas are 0.995 J/g•K and 0.622 J/g•K, respectively. How much heat is required to convert 2.500 kg of solid SO_{2} at the melting point to a gas at 60.°C?
