Calculate the work WC done by the gas during the isothermal expansion. Express WC in terms of p0, V0, and Rv.
mote1985 [20]

Complete Question

The complete question is shown on the first and second uploaded image

Answer:

The expression is  W_c =  P_o V_o ln (R_v)  

Explanation:

Generally smallest workdone done by  a gas is mathematically represented as

          dW  =  PdV

Generally for an isothermal process

    PV  =  nRT = constant

=>   P = \frac{nRT}{V}

Generally the total workdone is mathematically represented as

   W_c =  \int\limits^{v_f}_{V_o} {\frac{nRT}{V} } \, dV

=> W_c = nRT  \int\limits^{V_f}_{V_o} {\frac{1}{V} } \, dV

=>  nRT [lnV]   | \left \ {V_f}} \atop {V_o}} \right.

=>  W_c = nRT [ln(V_f) - ln(V_o)]

=>  W_c = nRT ln \frac{V_f}{V_o}

From the question \frac{V_f}{V_o }  =  R_v

=> W_c =  P Vln (R_v)

at initial  state

W_c =  P_o V_o ln (R_v)

What happens in a convection current?
V125BC [204]

Answer:

Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.
