Answer:
Explanation:
Given
saturated air temperature by [tex]0.5^{\circ}C/100 m[/tex]
Dew point temperature is given by [tex]t=2^{\circ}C[/tex]
Dew point is defined as the temperature after which air no longer to uphold the water vapor fuse with it and some water vapor may condense to a liquid.
air continues to rise for 1400 m
i.e. change in temperature would be [tex]\Delta t =\frac{0.5}{100}\times 1400=7^{\circ}C[/tex]
Final temperature [tex]t_f[/tex]
[tex]t_f+\Delta t=t[/tex]
[tex]t_f=2-7=-5^{\circ}C[/tex]
