Based on the thermodynamic properties provided for water, determine the energy change when the temperature of 0.650 kg of water
____ [38]
The boiling point of water is 100°C. So at 101°C, the water is steam. Compute the specific heat first from 101 to 100.

E = mCΔT, where c for steam is 1.996 kJ/kg·°C
E₁ = (0.65 kg)(1.996 kJ/kg·°C)(101 - 100°C) = 1.2974 kJ

Next, let's solve the latent heat when steam turns to liquid. The heat of vaporization of water is 2260 kJ/kg.

E₂ = mHvap = (0.65 kg)(2260 kJ/kg) = 1469 kJ

Lastly, let's solve the energy to bring down the temperature to 51°C. The specific heat of liquid water is 4.187 kJ/kg·°C.
E₃ = (0.65 kg)(4.187 kJ/kg·°C)(100 - 51°C) = 139.36 kJ

Thus,
<em>Total energy = 1.2974 kJ+1469 kJ+139.36 kJ = 1,609.66 kJ</em>

The ratio of the potential difference across a conductor to the current in the conductor is called
svetoff [14.1K]

Answer:

The ratio of the potential difference across a metallic conductor to the current in the conductor is known as.

B. Resistance.

Explanation:

According to ohms law   " the current  passing through a conductor is directly proportional to the potential difference between the ends provided the temperature of the wire remains constant".

What is resistance ?

Resistance is a measure of the opposition to current flow in an electrical circuit

what is a resistor ?

a resistor is a n electric conductor which forms resistance to free flow of electric current, the resistance is measured in Ω
