Those solutions in which there is no volume change upon mixing the components in the liquid state and which, when diluted do not undergo any heat change (i.e. heat of dilution is zero), are called __________ solutions.?
Answer: Option 1 For an ideal solution the heat of mixing or enthalpy change and volume change due to mixing is zero. Since volume change mixing $$ = {V^t}\left( {T,P} \right)...

How is M related to N Statements : I. P, who has only two kids, M and N, is the mother-in-law of Q, who is sister-in-law of N. II. R, the sister-in-law of M, is the daughter-in-law of S, who has only two kids, M and N.?
Answer: Option 1 From I, we conclude that P is the mother of M and N, while Q is the daughter-in-law of P and sister-in-law of N. Thus, Q is...

Fourier's law of heat conduction is (where Q = Amount of heat flow through the body in unit time, A = Surface area of heat flow, taken at right angles to the direction of heat flow, dT = Temperature difference on the two faces of the body, dx = Thickness of the body, through which the heat flows, taken along the direction of heat flow, and k = Thermal conductivity of the body)?
Answer: Option 1 Fourier's law of heat conduction is k. A. (dT/dx) where Q = Amount of heat flow through the body in unit time, A = Surface area of heat...

The compressibility factor of a gas is given by (where, V₁ = actual volume of the gas V₂ = gas volume predicted by ideal gas law )?
Answer: Option 1 The compressibility factor is given by $$Z = \frac{{P{V_1}}}{{RT}}.$$ If at the same temperature and pressure if the same gas exists as ideal gas than we...
