Ohm’s law describes the relationship between which quantities?
2 answers:
Answer: The quantities are Voltage, Current and Resistance.
Explanation: Ohm's Law is the law which directly relates Current with Voltage.
This law states that the current passing through two points of a conductor is directly proportional to the potential difference across the two points.
Mathematically,
Removing the proportionality sign by adding a constant Resistance, 'R'
where, V = Potential difference
I = Current
R = Resistance
Hence, the quantities which are related in this law are Current, Voltage and Resistance.

Answer:
17,890 J
Explanation:
The amount of heat released by a gaseous substance when it condenses is given by the formula
where
n is the number of moles of the substance
is the latent heat of vaporization
The formula can be applied if the substance is at its vaporization temperature.
In this problem, we have:
n = 0.440 mol is the number of moles of steam
is the latent heat of vaporization of water
And the steam is already at 100C, so we can apply the formula:
