Answer:
Since a sample of air at 35 ° C and 60% relative humidity holds 26.25 grams / cubic meter of water vapor. The same sample of air at 40 ° C can hold a maximum of 50 grams / cubic meter of water vapor. If the air currently holds 30 grams / cubic meter, then its relative humidity is 60%.
Explanation:
To solve the following question, the following calculations must be performed:
If 40ºC can have a maximum of 50 grams per cubic meter of water vapor, this would imply a total of 100% humidity. Thus, if 35º had 100% humidity, the amount of grams per cubic meter of water vapor would arise from the following calculation:
40 = 50
35 = X
35 x 50/40 = X
1750/40 = X
43.75 = X
Now, if this implies 100% humidity, to determine 60% humidity the following calculation must be carried out:
100 = 43.75
60 = X
60 x 43.75 / 100 = X
2625/100 = X
26.25 = X
Therefore, if with 100% humidity you have 50 grams per cubic meter of water vapor, with 60% humidity you would have 30 grams of water vapor per cubic meter.
The major factor that is based upon in ANOVA is the p-value. The null hypothesis is that the mean is the same for all groups. This could be rejected if according to statistical data analysis, the p-value is less than 0.5.

<u>(</u><u>Ans - </u><u>4</u><u>)</u>
(a) 1000 kg/ m^3
(b)
1) sink
2) float
3) sink
4) just float
(c) New density = 2 g/cc since both mass and volume of rock are halved.
(d) Ice floats because water in solid state undergoes hydrogen bond formation, which reduces its density and it starts to float.
