Answer:
i. Cv =3R/2
ii. Cp = 5R/2
Explanation:
i. Cv = Molar heat capacity at constant volume
Since the internal energy of the ideal monoatomic gas is U = 3/2RT and Cv = dU/dT
Differentiating U with respect to T, we have
= d(3/2RT)/dT
= 3R/2
ii. Cp - Molar heat capacity at constant pressure
Cp = Cv + R
substituting Cv into the equation, we have
Cp = 3R/2 + R
taking L.C.M
Cp = (3R + 2R)/2
Cp = 5R/2
Answer:
1. A glass of water at 80°C because the more heat it will recieve, the more temperature increases. Heat is a sort of energy so the more it is heated, the more energy the water will recieve. So in comparison to 20°C, 80°C has more energy in it because it has a higher temperature.
2. An aluminium can at 30°C because the more heat it will recieve, the more temperature increases. Heat is a sort of energy so the more it is heated, the more energy the aluminium will recieve. So in comparison to 20°C, 30°C has more energy in it because it has a higher temperature.

Answer:
i - component of V is zero for any value of t i-e no motion in this direction
Explanation:
Since
r= i+3
j+t k
==> V = 
=
=
and acceleration is given by taking derivative of velocity w.r.t t
==> a= 
=
=
so, V=0i+6tj+k
and
a = 0i+6j+k
i - component of V is zero for any value of t i-e no motion in this direction
Answer: D
Explanation: I took the test.
I accidentally posted a comment on it too, sorry about that.
