Answer:
Given that
P = RT/V + a/V²
We know that
H= U + PV
For T= Constant (ΔU=0)
ΔH= ΔU +Δ( PV)
ΔH= Δ( PV)
P = RT/V + a/V²
P V= RT + a/V
dH/dV = d(RT + a/V)/dV
dH/dV = - a/V²
So the expression of dH/dV
b)
In isothermal process
(ΔU=0)
Now by putting the all values
ΔH = 17.06 L.atm

Answer:
Everyone would get 2 1/4 cupcakes because if you split up each cupcake by 4, (In four different pieces) everyone would get 9/4 slices. Change to a mixed number to get 2 1/4
Explanation:
Answer:
∆v = 61.0 m/s
θ = 305°
Explanation:
Given;
initial velocity u= 50.0 m/s angle 270°
Final velocity v = 35.0 m/s angle 180°
∆v = v - u ........1
Resolving into x and y axis;
For y axis
∆vy = vsin180 - usin270
∆vy = 0 - (-50) = 50 m/s
x axis;
∆vx = vcos180 - ucos270
∆vx = -35 - 0= -35m/s
Magnitude of ∆v;
∆v = √(-35^2 + 50^2)
∆v = 61.0 m/s
Direction;
Tanθ = ∆vy/∆vx
θ = taninverse (50/-35)
θ = -55°
θ = 360-55 = 305°
Answer:
<h2>
<em><u>Joules</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>Watts</u></em><em><u> </u></em><em><u>×</u></em><em><u> </u></em><em><u>Seconds</u></em></h2>
Explanation:
If you multiply the number of watts by the number of seconds, you'll end up with joules.
