Watt needed to heat up an iron, correct?

In summary, the wattage needed to heat up an iron depends on factors such as the type of iron, amount of water, and initial temperature. On average, an iron requires 1200-1500 watts to heat up, but this can vary based on size and type. A higher wattage iron can save time in heating up due to its ability to generate more heat. It is generally safe to use a higher wattage iron as long as instructions are followed, but caution should be taken to prevent fire. Other factors that affect heating time include fabric type, initial temperature, and water level.

an IRON cube with (Length 1.3cm Width 1.3cm Height 0.7cm) so
Volume = 1.183cm^3

density of an IRON = 7.8gm/cm^3 so
Mass = 9.2274gram

Q=mcT c for iron = 0.450 J/(g·K), T difference = 160 degree celsius
Q=9.2 . 0.45 . 160
Q=662.4Joule

1Joule = 1 Watt.second

so if i need to heat up an IRON from 20C to 180C (T difference = 160 degree celsius) in 60second

so i need (662.4/60) = 11.04Watt

correct? please advice..

thanks

Yes that should be correct.
 

1. How is the wattage needed to heat up an iron determined?

The wattage needed to heat up an iron depends on several factors, including the type of iron, the amount of water in the iron, and the initial temperature of the iron. Generally, the higher the wattage, the faster the iron will heat up.

2. What is the average wattage needed to heat up an iron?

The average wattage needed to heat up an iron is around 1200-1500 watts. However, this can vary depending on the size and type of iron.

3. Can using a higher wattage iron save time when heating up?

Yes, using a higher wattage iron can save time when heating up. This is because higher wattage irons can generate more heat, allowing them to reach the desired temperature faster.

4. Is it safe to use a higher wattage iron?

As long as the iron is used according to the manufacturer's instructions, it is generally safe to use a higher wattage iron. However, it is important to be cautious and not leave the iron unattended, as a higher wattage can also mean a higher risk of fire.

5. Are there any other factors besides wattage that affect how quickly an iron heats up?

Yes, besides wattage, the type of fabric being ironed, the initial temperature of the iron, and the amount of water in the iron can also affect how quickly an iron heats up. For example, thicker fabrics may require a higher wattage iron to heat up efficiently.
