Aspace shuttle moves through the atmosphere on its return from space. at point 1 on its wing, the air temperature and pressure are measured to be t1 = 300°c and p1 = 10,000 pa while at point 2 they are t, = 700°c and p2 = 575,000 pa. calculate the air density in kg/m3 at both points 1 and 2.

The air density in at points 1 is and 2 is .

Explanation:

Average molecular weight of an air ,M= 28.97 g/mol

or

P = Pressure of the gas

n = moles of gas

T = Temperature of the gas

d = Density of the gas

M = molar mass of the gas

R = universal gas constant

Density at point-1 =

M = 28.97 g/mol

1 g = 0.001 kg

Density at point-2 =

M = 28.97 g/mol

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
