Answer #1

1. FICK'S LAW

ANSWER: A. T GRADIENT

EXPLANATION: IN SIMPLE TERMS, FICK'S LAW STATES THAT SOLUTES FROM REGION OF HIGHER CONCENTRATION TO LOWER CONCENTRATION.

2. 20mm between two plates 1000 °C and 50 °C. heat transfer will be

ANSWER: A. RADIATION

EXPLANATION: RADIATON IS THE MODE OF HEAT TRANSFER WHICH DOES NOT REQUIRE A MEDIUM. IN THE ABOVE QUESTION THE TWO PLATES ARE SEPARATED, THEREFORE MODE OF HEAT TRANSFER WILL BE THROUGH RADIATION.

3. cavitation is caused by?

ANSWER: C. OTHER

EXPLAINATION: CAVITIES OR VOIDS ARE FORMED IN THE LIQUID WHERE THE PRESSURE IS RELATIVELY LOW. WHEN THEY ARE SUBJECTED TO HIGHER PRESSURE THEY EXPLODE.

Thermodynamics: Consider the equilibrium reaction A(g) + B(g) -><- C(g)+D(g). At T=298 K, the standard enthalpies of formation of the components in the gas phase are -20, -40, -30, and -10 kJ/mol for A,B,C, and D, respectively. The standard-state entropies of the components in the gas phase are 30, 50, 50, and 80 J/(mol K), in the same order. The vapor pressure of liquid C at this temperature is 0.1 bar, while all other components are volatile gases with Henry's...
