Answer: Option (c) is the correct answer.
Explanation:
Temperature is used as for measuring the average kinetic energy present in a substance or object.
The internal kinetic energy obtained by the molecules of an object is known as thermal energy.
Hence, temperature measures the thermal energy of an object.
Whereas when this thermal energy flows from a hotter object to a cooler object which are placed adjacent to each other then it is known that heat is flowing.
Thus, we can conclude that heat differ from temperature as temperature measures thermal energy, and heat is the flow of thermal energy.
Use the van der Waals equation and the ideal gas equation to calculate the volume of 1.000 mol of neon at a pressure of 500.0 atm and a temperature of 355.0 K.
The Van der Waals equation, also known as the Van der Waals equation of state, is an equation of state used in chemistry and thermodynamics that extends the ideal gas law to take into account the effects of molecular interaction as well as the finite size of the molecules in a gas.
We may build a new equation that better reflects real gas behavior by modifying the ideal gas law to include corrections for interparticle attractions and particle volumes. The van der Waals equation can be used to determine a gas's properties under less-than-ideal circumstances.

Answer:
V2= 0.0796m3
Explanation:
We have that for a real gas the following relation is fulfilled:
PV / T = constant
To use this formula I need to pass the pressure of mmHg to KPa and the volume of L to m3, knowing that
1Kpa = 7.50062mmHg
1L = 0.001m3
So i can say
P1V1/T1 =P2V2/T2
So
V2= P1V1T2/P2T1
V2= 51.60KPa*0.034m3*350k/36.53KPa*211k
finally
V2= 0.0796m3
The deltaHrxn = -243 kJ/mol the deltaHrxn of CH4(methane) = -802 kJ/mol
The fuel that yields more energy per mole is METHANE. The negative sign merely signifies the release of energy. Thus, 802 kJ/mol is greater than 243 kJ/mol.
The fuel that yields more energy per gram is HYDROGEN. Here is the computation:
deltaHrxn = (-243 kJ/mol)(1 mol/2.016 g H2) <span>= -120.535714286 kJ/g or -121 kJ/g
</span>deltaHrxn of CH4(methane) = (-802 kJ/mol)(1 mol/16.04 g)
<span>= -50 kJ/g
</span>
As discussed the negative sign serves as the symbol of released energy. Thus, 121 is greater than 50.
Answer:
Partial pressure of Ne is 0.61 atm.
Explanation:
Mole fraction of a gas 
in mixture = (no. of moles of the gas in mixture)/(total no. of moles of gases in mixture)
Here, total no. of moles of gases = (0.32 + 0.56) moles = 0.88 moles
So, mole fraction of Ne in mixture, 
Let's assume both He and Ne along with their mixture behaves ideally,
Hence, in accordance with Dalton's law of partial pressure-
Where, 
and 
are partial pressure of Ne and total pressure respectively.
So, 
So, partial pressure of Ne is 0.61 atm.
