Compute the specific heat capacity at constant volume of nitrogen (N2) gas. The molar mass of N2 is 28.0 g/mol.
goldfiish [28.3K]

Answer:Specific heat capacity at Constant volume of Nitrogen =742.32JKg.K

Explanation:

The Specific heat capacity at Constant volume of an ideal gas is given as

c =Cv / M

Cv= Constant volue of gas

M= Molar mass

But  First, we determine the Constant volume, Cv  which is given as

Cv = 5/2R since Nitrogen is a diatomic gas, N2 where R= 8.314Jmol.k

= 5/2 x 8.314Jmol.K

=20.785Jmol.K

Specific heat capacity at Constant volume, c

c= Cv/M

M=molar mass = 28.0 g/mol.

changing to kg/mol =28/1000= 0.028kg/mol

Therefore c =20.785Jmol.K/0.028kg/mol

=742.32JKg.K

<h3>Answer:</h3>

B. The object moves some distance

<h3>Explanation:</h3>
  • Work is the product of force and distance.
  • Work is done on an object when a force is applied on the object making it move some distance.
  • For example; If a mason applies a force of 5 N to move a stone at a distance of 10 m, then the work done will be 50 Joules.
  • Applying a force on an object without making it move some distance then there is no work done.
  • Consider a boy pushing a wall really hard and the wall doesn't move even for a single inch, this means there is no work done.
