Question

Only need help with a, d, and e

Can you use an alcohol thermometer to measure the temperature of a flame? Why? Translate this statement "The fluid pressure must be the same at any points at the same height in a continuous fluid." in Chinese. A process may be operated at steady state or transient state. What is the difference between these two operation states? Can the density of a substance be directly measured? If not, how can you obtain the density of an unknown solid? Ideal gas law shows that PV = nRT, where P: gas pressure, V: gas volume, n: number of moles of the gas, T: gas temperature, and R: gas constant. It was known that at standard conditions (T = 0 degree C and P = 1 atm), ideal gas has a specific volume of 22.415 L/mol. What is the numerical value of R in psi-ft^3/(lb-mol degree R)? Is "weight" a basic dimension or a derived dimension? Is there any difference between "weight" and "mass"?

Explanation / Answer

Answer for a.

No, it is just useful for measuring day and night-time and body temperature, although not for anything much hotter than these. Only we can use particuler alcohol boiling point not more than that, if we will use, it will balst.

Answer for d.

just get its weight and the volume
and then to get the density use the formula

D = MASS / VOLUME
