Answer 1

Hey mate..
Here is your answer

Its answer is one..

As Heat at constant volume is 0.075 calories..

As it is absorbed 1g in 1° Celsius temperature at constant volume .

Hence one mole os gram is 40(0.075) which is equal to 3 cal..
Here Cp -Cv is equal to R
and Cp is equal to 5..

So,
Then Cp-Cv is equal to 5 /3 which is equal to approximately 1....

Hope it will help you my friend

Answer 2

Heya ✌✌
Here is u r Ans ➡

✨Specific heat of gas at constant volume = 0.075 calg^ -1C°

⭐0.075 cal is absorbed by 1 g of it for 1° rise in temperature at constant volume

So, Total Heat Absorbed by 1 g Mole of The Gas is

40 ( 0.075) = 3cal

Since, Cp - Cv = R ... or Cp = 5
Cp / Cv = 5 / 3

And Hence The Gas is Monatomic .

Ans ➡ (a) one
