Okay, so the question i want us to find the power output of a microwave oven.
00:06
Okay, so we know power can be equal to heat divide by time in this case, okay? and heat can be equal to mcdlt.
00:17
So power can be equal to mcdlt divided by the lowercase t.
00:23
The mass of the water in this case is 0 .3 kilograms if you convert from 430 grams, okay? and specifically for the water is 4 ,184g.
00:33
Per kilogram in 10k, kelvin.
00:36
The changing temperature is from 20 degrees celsius to the volume points, which is 100 degrees celsius.
00:41
So it's 100 degrees celsius plus 273, minus 20 degrees celsius plus 273, and we'll get 80 kelvin.
00:48
It's a changing temperature, ok? but if you just want to use 100 degrees celsius minus 20 degrees celsius, you still get the same result, which is 80, but it's in degrees celsius...
