Question
Convert the following: 102.4 kPa = _____ mb = ____ mm mercury = ___ inches For the maximum and minimum temperatures in degrees Fahrenheit (degree F) (first row of values below), covert to degrees Celsius (degree C) and Kelvin (K). Maximum 67 degree F ____ degree C _____ k Minimum 35 degree F _____ degree C _____ K Energy is the ability to do work and is defined as the product of force and the distance over which that force is applied. It is typically expressed in units of Joules (J), which is the amount of energy spent when 1 N of force is applied over a 1 m distance. Another way to define energy is with the units of calories (cal), which is the amount of energy necessary to raise 1 cubic centimeter of water by 1 degree C. The rate of energy change is typically expressed in Watts (W), or J per second (J s^-1) and is known as power. Both energy and power are often expressed per unit area (divided by m^2). Express the solar constant (a measure of radiation, discussed in Lab 4), equal to 1.96 cal cm^-2 min^-1, in units of W m^-2. ______W m^-2Explanation / Answer
11) 102.4 kilopascal(kPa)= 1024 milibar(mb)= 768.0631 milimeter of mercury(mm mercury)= 30.2387 inches of mercury(inHg).
N.B.- last term in the question must be inHg not inches.
12) maximum
67 degree Fahrenheit
19.45 degree Celsius
292.594 Kelvine (K)
Minimum
35 degree Fahrenheit
1.67 degree Celsius
274.82 Kelvine (K)
EXTRA QUESTION:
1) we know (see also in the question) that 1Joules/second= 1Watt.
Now, 1.96 calories/centi-meter2minutes= 8200.64 joules/cm2min=136.6773 J/cm2sec=136.6773 W/cm2= 1366.773W/m2
