The water displacement method is a set of measurements used to calculate the volume of an irregularly shaped object. These objects are commonly known as irregularly shaped solids.
<h3>What is water displacement method ?</h3>
The displacement method (also known as the submersion or dunking method) can be used to accurately measure the volume of the human body and other irregularly shaped objects by measuring the volume of fluid displaced when the object is submerged.
Place your jewelry on a table or in your hand, and pour some white vinegar directly on the metal (a dropper can also be used). If the metal of the jewelry changes color, it is not pure gold; if it continues to shine, you have real gold in your hand.
Thus, The water displacement method is a set of measurements used to calculate the volume of an irregularly shaped object.

Answer:
Explanation:
From the question we are told that:
Pressure 
Temperature 
Volume 
Heat Produced 
Generally the equation for ideal gas is mathematically given by
Therefore
Since
Heat of combustion of Methane=889 kJ/mol
Heat of combustion of Propane=2220 kJ/mol
Therefore
Comparing Equation 1 and 2 and solving simultaneously
Therefore
Mole fraction 0f Methane is mathematically given as
Answer:
Before we get into the first law of thermodynamics we need to understand the relation between heat and work and the concept of internal energy. Just like mass, energy is always conserved i.e. it can neither be created nor destroyed but it can be transformed from one form to another. Internal energy is a thermodynamic property of the system that refers to the energy associated with the molecules of the system which includes kinetic energy and potential energy.
Whenever a system goes through any change due to interaction of heat, work and internal energy, it is followed by numerous energy transfer and conversions. However, during these transfers, there is no net change in the total energy.
Similarly, if we look at the first law of thermodynamics it affirms that heat is a form of energy. What it means is that the thermodynamic processes are governed by the principle of conservation of energy. The first law of thermodynamics is also sometimes referred to as the Law of Conservation of Energy

Answer: Crescent
Explanation: Image result for In what phase is the moon if it is gaining light and less than half illuminated
Crescent Moons are when it's less than half illuminated, and gibbous when it's more than half. “Waxing” means that the Moon becomes more illuminated night-by-night, and the term “waning” means that it's getting less illuminated each night.
