A conventinal light bulb is rated at 240 V (100 W).Ligths is emitted when the filament of the bulb gets whites hot.How many joules of energy does bulb transform each minute?

A Joule is a measure of energy. A Watt is a measure of energy per time.

More specifically, a Watt = 1 Joule per second.

So, your 100 Watt bulb uses 100 Joules per second.

60 seconds per minute. So, each minute, your bulb transforms 6000 Joules of electrical energy into light (and heat).

To determine the amount of energy transformed by the bulb each minute, we need to calculate the power consumption per minute and then convert it to joules.

First, let's convert the power rating of the bulb from watts (W) to kilowatts (kW) since energy is commonly measured in kilowatt-hours (kWh).

Power (in kW) = Power (in W) / 1000
Power = 100 W / 1000 = 0.1 kW

Next, we need to calculate the energy consumption per minute. Since power is the rate at which energy is consumed or transformed, we can use the formula:

Energy (in kWh) = Power (in kW) x Time (in hours)

Since we want the energy consumed per minute, we need to convert the time from minutes to hours.

Energy (in kWh) = Power (in kW) x (Time (in minutes) / 60)

Energy (in kWh) = 0.1 kW x (1 min / 60)

Energy (in kWh) = 0.1 kW x 0.0167 hours

Energy (in kWh) = 0.00167 kWh

Finally, we need to convert kilowatt-hours (kWh) to joules (J). One kilowatt-hour is equal to 3.6 x 10^6 joules.

Energy (in J) = Energy (in kWh) x Conversion factor (3.6 x 10^6 J/kWh)

Energy (in J) = 0.00167 kWh x 3.6 x 10^6 J/kWh

Energy (in J) = 6012 J

Therefore, the conventional light bulb transforms approximately 6012 joules of energy each minute.
