Some more questions

1.) Calculate the number of electrons passing per second through the cross section of a wire conducting the current of 0.1 mA.

2.) Find the difference of heat capacities C_p and C_v of 6g of H₂ at normal conditions. Give the answer in J K^{-1

3.) A 1L vessel contains 1 mole of O₂ . If the root mean square speed in x direction O₂ molecules is <v_x²>^1/2=200 m s^-1 find the pressure (in N/m²) in the vessel

4.)}For water the latent heat of fusion is 3.3x10⁵ J kg^-1, the latent heat of vaporisation is 2.3x10⁶ J kg^-1 , and the heat capacity of liquid water is 4.2x10³ J kg^-1 K^-1 . How much heat is (in kJ) required to boil 2kg of ice initially at 0C⁰?

Any guidance appreciated
