Answer:

It takes 266 seconds to melt the ice.

Explanation:

Given data

  • Power of the microwave oven (P): 125 Watt
  • Heat supplied to the ice (Q): 33,200 Joule
  • Time for the melting (t): to be determined

In order to determine the time required to melt the ice, we can use the following expression.

P = Q/t

t = Q / P = 33,200 J/ 125 W = 266 s

It takes 266 seconds to melt the ice.

It will take 266 seconds for the ice cube to melt.

We were given the

Power of the microwave oven (P) = 125 Watt

Heat supplied to the ice (Q) = 33,200 Joule

Time for the melting (t) = ?

We can then use the formula which is

P = Q/t

where P is power, Q is heat energy and t is time

t = Q / P

= 33,200 J/ 125 W = 266 s

Therefore it will take 266 seconds for the ice to melt.
