Part 1: Describe the mass and surface temperature of the supergiant stars. Part 2: Explain where on the HR diagram you would expect to find a supergiant star based on its physical properties.

i think the answer is

mass

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a
