If the change in enthalpy is -5074.1 kj , how much work is done during the combustion?

baherus [9]

Hence,
<span>∆H = ∆U + W </span>
<span>=> </span>
<span>W = ∆H - ∆U </span>
<span>= -5074 kJ - (-5084.) kJ </span>
<span>= 10 kJ</span>

A particle with a charge of -4.0 μC and a mass of 3.2 x 10-6 kg is released from rest at point A and accelerates toward point B,

Assoli18 [71]

Answer:

$V_B-V_A=-20736-0=-20736volt$

Explanation:

We have given charge on the particle $q=-4\mu C=-4\times 10^{-6}C$

Mass of the charge particle $m=3.2\times 10^{-6}kg$

From energy of conservation kinetic energy will be equal to potential energy

So at point A

$\frac{1}{2}mv^2=qV$

At point a velocity is zero

So $\frac{1}{2}(3.2\times10^{-6} )0^2=-4\times 10^{-6}V_a$

$V_A=0volt$

At point B velocity will be 72 m/sec

So $\frac{1}{2}\times 3.2\times 10^{-6}72^2=-4\times 10^{-6}V_b$

$V_B=-20736volt$

So $V_B-V_A=-20736-0=-20736volt$
