Can we measure the absolute value of internal enegry?

Can the absolute value of internal energy be determined ? Why or why not ?

The absolute value of cos x is

Assertion :- Absolute value of enthalpy can not be determined. Reason :- Enthalpy is defined as H = E + PV, and value of internal energy can not be determined absolutely therefore absolute value of enthalpy can not be determined.

Find the absolute value of -(12)/(29)

Find the absolute value of (23)/(17)

Find the absolute minimum value of |x|

Correct the following statements by changing the underlined part of the sentence (Do not change the whole sentence) Absolute value of single electrode potential ul("can be easily determined.")

Can the absolute value of refractive index of a medium be less than unity ?

The work done by a system is 10J , when 40J heat is supplied to it. Calculate the increase in the internal enegry of system.

The enthalpy change for chemical reaction is denoted aas DeltaH^(Theta) and DeltaH^(Theta) = H_(P)^(Theta) - H_(R)^(Theta) . The relation between enthalpy and internal enegry is expressed by equation: DeltaH = DeltaU +DeltanRT where DeltaU = change in internal enegry Deltan = change in number of moles, R = gas constant. For a reaction, 2X(s) +2Y(s) rarr 2C(l) +D(g), DeltaH at 27^(@)C is -28 kcal mol^(-1). DeltaU is ..... kcal mol^(-1)
