I was assigned an example problem today and i can do the math, look at my tables and get the right answer no problem. What i want to understand, is why when specific volume increases for r134a, that it means its supper heated?

My given value for sv was .1384m3/kg which is above the .09 in the table. I get that if its above, then it means superheated. Looking at the saturation dome, i see why, but scientifically, i dont. I asked a couple of professors and i didnt understand their answer. They were trying to inform me about how the gas takes up more space... i get that, but how does taking up more space mean superheated?

Thanks
