The efficiency of an ideal heat engine working between the freezing point and boiling point of water, is :-

Every business needs to take the decision regarding the investment in current assets i.e. the working capital. Current assets refer to the assets that are converted into cash or cash...

(D) Combustion of Liquefied Petroleum Gas (LPG)

(c) Reach absolute zero temperature.  We cannot reach absolute zero temperature.

(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...

(d) : It does not violate first law of thermodynamics but violates second law of thermodynamics.

(d) Only statement 3 is correct. An air conditioner (often referred to as AC) is a home appliance, system, or mechanism designed to dehumidify and extract heat from an area....

(c) Statement 1 and 3 contradict each-other, hence both statements cannot be true together. But there are a situation where in both statements are false that is if some of...

(b) For endothermic reaction, ΔH=+ve. Now, ΔG=ΔH-TΔS ΔG will be +ve when ΔH and ΔS both are +ve and temperature is low so that ΔH> (-TΔS). ΔG will be –ve When...

c) Prolonged electrolysis of water
