The boiling point of alcohol is 780C. What will be the temperature in Kelvin scale?

(C) 5% – 8% acetic acid in water

(c) : According to Raoult’s law equimolal solutions of all the substances in the same solvent will show equal elevation in boiling points as well as equal depression in freezing...

(b) : For endothermic reaction, ΔH = +ve Now, ΔG = ΔH – TΔS For nonspontaneous reaction, ΔG should be positive Now ΔG is positive at low temperature if ΔH is positive. ΔG is negative...

efficiency = (T1 - T2 / T1) * 100 efficiency = 100/ 373 * 100 efficiency = 26.8

(d) Normal body temperature of human is 37° C. But when we convert 37° C into Kelvin it becomes 310 K because 0° C = 0°C + 273 = 273...

Because for boiling to occur vapour pressure of organic compound & steam should be equal to atmospheric pressure. As vapour pressure of water is higher than organic liquid. Therefore, organic...

(A) S.I. unit of temperature is Kelvin.

(i) Brown fumes. white residue. (ii) Decomposition reaction  2Pb(NO3)2 →2PbO+4NO2+O2

(iv) Assertion and reason both are incorrect statements.
