Yes; you need to know how long the light bulb is on.
<h3>How much electricity does a light bulb use?</h3>
Because of this, lower wattage bulbs are sometimes referred to as "equivalent to 60W"; nevertheless, what is equal is brightness, not energy consumption.
Converting wattage to kilowatts is the best way to determine how much energy your lightbulb consumes. Thus, 0.1 kW would be needed per hour for a 100W light bulb.
Incandescent (up to 100W) and halogen (up to 120W) light bulbs with higher energy consumption are being phased out. You may get ornamental exposed carbon filament light bulbs, which are normally 40–60W, if you still have any of them operating in your house.

The answer is Solid.
This is on account of the substances that develop a solid are packed in a settled, firmly pressed geometric plan.
Answer:
3.23 L
Explanation:
Using the combined gas law formula as follows:
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressure (atm)
P2 = final pressure (atm)
T1 = initial temperature (K)
T2 = final temperature (K)
V1 = initial volume (L)
V2 = final volume (L)
According to the provided information in this question;
P1 = 1.26atm
P2 = 3.14atm
V1 = 6.5L
V2 = ?
T1 = 150°C = 150 + 273 = 423K
T2 = 250°C = 250 + 273 = 523K
Using P1V1/T1 = P2V2/T2
1.26 × 6.5/423 = 3.14 × V2/523
8.19/423 = 3.14V2/523
0.0194 = 3.14V2/523
Cross multiply
3.14V2 = 523 × 0.0194
3.14V2 = 10.146
V2 = 10.146/3.14
V2 = 3.23L
Mass : actual amount of material contained in a body. It is independant of where you are.
Weight: force that gravity puts on a mass.
On Earth, gravity is 9.80 m/s^2compared to 1.62 m/s^2 on the moon.
Weight=mass *gravity
Moon : (example)
10 kg* 1.62 m/s^2= 16.2 N ( Newton is the unit for weight)
Earth:
10*9.80= 98 N
