Answer:
12.3kPa
Explanation:
Using Dalton's law which states: in a mixture of gases the total pressure is equal to the sum of the pressures of all gases present. In this question,
Total Pressure = Pressure of Hydrogen + Pressure of water vapor
Pressure of Hydrogen = 122.4kPa
Total Pressure 134.7kPa.
Pressure of water vapor = Total pressure - Pressure of Hydrogen =
134.7kPa - 122.4kPa = 12.3kPa.
Vapor pressure of water at certain temperatures is is usually available in vapor pressure table. In this question temperature here is 323 K.
Convert 323 K to celsius (using the formula Celsius = K -273) will give us 323 k -273 = 50 degrees celsius. Checking the vapor pressure of water at 50 degrees celsius will show you 12.34kPa
Answer:
Air masses tend to move from west to east.
The eastern time zone would the opposite side of the angle made by his car. So this means he would be traveling 30cos30 m/s completely in the east direction. Or approximately 26 m/s in the East direction. 5000 m divided by this answer results in approximately 192 seconds. I would use a calculator to get a more exact answer
Answer: All of our energy comes from the sun, which is our nearest star. The sun sends out huge amounts of energy through its rays every day. We call this energy solar energy or radiant energy. Without the sun, life on earth would not exist, since our planet would be totally frozen.
Answer:
1kg steam will have the maximum energy
