An electric rod of 2000 watts rating boils a certain quantity if water in 10 minutes, the heat is generated for boiling this water is?

answer is 12 X 10^5 Joules, but I cant solve it please solve it

10 min = 600 seconds

2,000 watts * 600 seconds = 1,200,000 Joules = 1.2*10^6 = 12 * 10^5

Thanks Sir, It helped me solve my MCAT questions

To calculate the heat generated for boiling the water, we need to use the power formula:

Power = Energy / Time

Given:
Power rating of the electric rod = 2000 watts
Time = 10 minutes = 10 x 60 seconds = 600 seconds

We know that 1 watt is equal to 1 joule per second.

Substitute the given values into the formula:

2000 watts = Energy / 600 seconds

Multiply both sides of the equation by 600:

2000 watts x 600 seconds = Energy

Energy = 1,200,000 joules

Therefore, the heat generated for boiling this water is 1,200,000 joules or 12 x 10^5 joules.

To solve this problem, we need to use the formula for calculating energy:

Energy (in Joules) = Power (in Watts) x Time (in seconds)

In this case, the power of the electric rod is given as 2000 watts, and the time taken to boil the water is given as 10 minutes. However, we need to convert the time into seconds because the power is given in watts (which is in terms of seconds).

1 minute = 60 seconds

Therefore, 10 minutes = 10 x 60 = 600 seconds

Now, we can use the formula to calculate the energy:

Energy = 2000 watts x 600 seconds = 1,200,000 Joules

Hence, the heat generated for boiling this water is 1,200,000 Joules, which can also be written as 12 x 10^5 Joules.
