A substance has density ρ, mass m, and volume V. If the volume is tripled, what is the new mass?
Igoryamba

Since the density of the substance is ρ (rho),

==> every cm³ of this substance has ρ grams of mass.

Then

==> V cm³ of it has ρV grams of mass.  That's ' m '.

and

==> 3V cm³ of it has 3ρV grams of mass.  That's ' <em>3m</em> '.

One mole of a gas is placed in a closed system with a 20 L vessel initially at T = 300 K. The vessel is then isothermally expand
Elden [556K]

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

\dfrac{dH}{dV}=\dfrac{-a}{V^2}

b)

In isothermal process

\Delta H=nRT\ln{\dfrac{V_2}{V_1}}      (ΔU=0)

Now by putting the all values

\Delta H=nRT\ln{\dfrac{V_2}{V_1}}

\Delta H=1\times 0.08206\times 300\ln{\dfrac{40}{20}}

ΔH = 17.06 L.atm
