Answer:

Remember Ohms law (the holy grail of electronics): V=IR

Explanation:

V=IR, where:

V=Voltage

I=Current

R=Resistance.

Looking at the equation (V=IR),

if R remains constant, but V is double, that means that the current has to also double, in order to keep the equation true.

Answer: the Current will double if voltage is doubled and resistance is kept constant.

Answer:

Work = - 4175.23 J

Heat Transfer = -4175.23 J

Explanation:

The work done in an isothermal process, is given by the following formula:

W = RT ln (P1/P2)

where,

W = Work done

R = Universal Gas Constant = 8.314 J/mol.k

T = Constant Temperature = 300 K

P1 = initial pressure = 150 KPa

P2 = final pressure = 800 KPa

using these values, we get:

W = (8.314 J/mol.K)(300 k) ln (150/800)

Here, negative sign shows that work is done on the system.

In isothermal process, from 1st law of thermodynamics:

Heat Transfer = Q = W (Since change in internal energy is zero for isothermal processes)

Here, negative sign shows that heat is transferred from the system to surrounding.

Answer:

Between 5 & 10 MPa in Table B.1.4

Explanation:

150F = 65°C

State 1:

T = 65°C , x = 0.0; Table B.1.1: v = 0,001020 m^3 /kg

Process: T = constant = 65°C

State 2:

T, v = 0.99 x v f (65°C) = 0.99 x 0,001020 = 0.0010098 m^3 /kg

Between 5 & 10 MPa in Table B.1.4
