## Engineering Thermodynamics According to Avogadro’s law

The sum of partial pressure of the mixture of two gases is sum of the two
Equal volumes of all gases, at the same temperature and pressure, contain equal number of molecules
All of these
The product of the gas constant and the molecular mass of an ideal gas is constant

## Engineering Thermodynamics The mass of flue gas per kg of fuel is the ratio of the

Mass of oxygen in 1 kg of flue gas to the mass of oxygen in 1 kg of fuel
Mass of carbon in 1 kg of flue gas to the mass of carbon in 1 kg of fuel
Mass of carbon in 1 kg of fuel to the mass of carbon in 1 kg of flue gas
Mass of oxygen in 1 kg of fuel to the mass of oxygen in 1 kg of flue gas

## Engineering Thermodynamics The gas turbine cycle with regenerator improves

Thermal efficiency
None of these
Avoid pollution
Work ratio

## Engineering Thermodynamics The efficiency of the Carnot cycle may be increased by

Decreasing the highest temperature
Increasing the highest temperature
Keeping the lowest temperature constant
Increasing the lowest temperature

## Engineering Thermodynamics If in the equation pvn = C, the value of n = ∝, then the process is called

Constant volume process
Constant pressure process
