Answer:
volt, unit of electrical potential, potential difference and electromotive force in the metre–kilogram–second system (SI); it is equal to the difference in potential between two points in a conductor carrying one ampere current when the power dissipated between the points is one watt.
The volts (symbol V) measure the different potential energy that exists between one point and the other. The volts are thus named in honor of Alessandro Volta, the inventor of the battery.
Batteries move anions (negatively charged things) and cations (positively charged things) to opposite terminals, creating a voltage. Voltage is better expressed as electric potential.
Voltage is the electrical force that causes free electrons to move from one atom to another. Just as water needs some pressure to force it through a pipe, electrical current needs some force to make it flow. "Volts" is the measure of "electrical pressure" that causes current flow.
The correct answer would be
Mile
3) a stretched rubber band
The given statement"If the pressure of a gas sample is quadrupled and the absolute temperature is doubled" is false.
Answer: Option B
<u>Explanation:</u>
As we know the direct relationship between Pressure and Temperature by the Gay-Lussac’s Law,
From this, we get,
So, according to given statement, we have 
Then from the above expression, we can find out the value of 
when pressure increased by 4 times of initial pressure as,
Hence, we get,
Hence, from the above expression we can say that as we increase the pressure four times, the temperature does not get doubled. So, the given statement in the question is false.
