Since power, P, equals iV, P/V = i, so at 120 V, a 40-watt bulb draws 1/3 A.

Answer:
The answer to your question is V2 = 0.203 kPa
Explanation:
Data
Volume 1 = V1 = 1l
Pressure 1 = P1 = 101.3 kPa
Volume 2= V2 = ?
Pressure 2 = 500 kPa
Process
- Use the Boyle's law to solve this problem
P1V1 = P2V2
-Solve for V2
V2 = P1V1/P2
-Substitution
V2 = (101.3 x 1) / 500
-Simplification
V2 = 101.3 / 500
-Result
V2 = 0.203 kPa
Answer:
Final volume is 3.50L
Explanation:
It is possible to find volume of a gas using combined gas law:
<em>Where P is pressure, V is volume and T is temperature of 1: initial state and 2: final state</em>
If initial state of the gas is:
1.75L of a gas is at 700K and is under 250kPa of pressure
And final state is:
298K and 53.2kPa.
Replacing:
0.625L = 0.1785*V₂
<em>3.50L = V₂</em>
Thus, <em>final volume is 3.50L</em>
