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.
What substances? Depends on their density, the lower density floats on top. For example, oil floats on top of water
Answer:
(a). The maximum loss of water vapor by the person is 
(b). The partial pressure of water vapor is 
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

Put the value into the formula



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



Put the value into the formula



Hence, (a). The maximum loss of water vapor by the person is 
(b). The partial pressure of water vapor is
