If a gas at 25.0 °C occupies 3.60 liters at a pressure of 1.00 atm, what will be its volume at a pressure of 2.50 atm?
Llana [10]
Since the temperature is constant, therefore, this problem can be solved based on Boyle's law.
Boyle's law states that: " At constant temperature, the pressure of a certain mass of gas is inversely proportional to its pressure".

This can be written as:
P1V1 = P2V2
where:
P1 is the initial pressure = 1 atm
V1 is the initial volume = 3.6 liters
P2 is the final pressure = 2.5 atm
V2 is the final volume that we need to calculate

Substitute with the givens in the above mentioned equation to get the final volume as follows:
P2V1 = P2V2
1(3.6) = 2.5V2
3.6 = 2.5V2
V2 = 3.6 / 2.5 = 1.44 liters

You have the same two resistors on a 10 volt series circuit. Will the voltage going into the second resistor be more, less, or t
Keith_Richards [23]

both resistance will have same voltage across it which is equal to 5 volt.

if resistance value is different then voltage drop across them will be different.

current in both resistance would be same.

let's say resistance is 5 ohm of each one.

total current = total voltage / total resistance

= 10 /(5+5) = 10/10 = 1 amp

now voltage across 5 Ohm resistance = current × resistance = 1× 5 = 5 volt
