Y=k/x, x is halved.<br> what happens to the value of y
IgorLugansk [536]

Answer:

y is doubled

Explanation:

If x is halved, that means the value is doubled. Here is an exmaple:

y=1/2. If the denominater is doubled, y would equal y=1/1. So, the value of y has doubled from 0.5 to 1. Therefore, if the denominator is halved, the solution will be doubled.

Air in human lungs has a temperature of 37.0°C and a saturation vapor density of 44.0 g/m³.
ioda

Answer:

(a). The maximum loss of water vapor by the person is 8.8\times10^{-2}\ g

(b). The partial pressure of water vapor is 6.29\times10^{3}\ N/m^2

Explanation:

Given that,

Temperature = 37.0°C

Volume of air = 2.00 L

Density of vapor = 44.0 g/m³

We need to calculate the maximum loss of water vapor by the person

Using formula of density

m=\rho_{air}\times V_{air}

Put the value into the formula

m=44.0\times2.00\times10^{-3}

m=0.088\ g

m=8.8\times10^{-2}\ g

(b). We need to calculate the partial pressure of water vapor

Using formula of pressure

PV=nRT

P=\dfrac{nRT}{V}

P=\dfrac{\rho\times R\times T}{M}

Put the value into the formula

P=\dfrac{44\times8.314\times(37+273)}{18.01528}

P=6294.82\ N/m^2

P=6.29\times10^{3}\ N/m^2

Hence, (a). The maximum loss of water vapor by the person is 8.8\times10^{-2}\ g

(b). The partial pressure of water vapor is 6.29\times10^{3}\ N/m^2
