Problem $1-1$:

Consider the low$-$speed flight of the Space Shuttle as it is nearing a landing. If the air pressure and temperature at the nose of the shutlle are $1\mathrm{.}2$ atm and $300$ K $,$ respectively, what are the density and specific volume?

Problem $1-2$:

Calculate the weight of air $($in pounds$)$ contained within a room $20$ fl long, $15$ it wids and $8$ ft high. Assume standard atmospheric pressure and temperature of $2\mathrm{.}1161bAt{l}^2$ and $59F,$ respectively.

Probiem $1-3$:

Comparing with the case of problem $1-2.$ calculate the percentage change in the total weight of air in the room wiven the air temperature is reduced to $-10F,$ assuming the pressure remains the same at $2,116lbat{r}^2.$
