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.
