An ice cube is placed in a microwave oven. Suppose the oven delivers 105 W of power to the ice cube and that it takes 30,200 J to melt it. How long does it take for the ice cube to melt?

Answer :

It will take 287.6 seconds for the ice cube to melt under the given conditions. This can be solved using the concept of heat.

What is melt?

Melt is a process in which a solid material is heated to its melting point, causing it to become a liquid. It is a physical process that occurs when a material is heated beyond its melting temperature, resulting in the formation of a liquid.

The amount of time it takes for the ice cube to melt depends on the mass of the ice cube.

The equation to calculate this is:

Time (in seconds) = (30200 J) / (105 W x Mass of Ice Cube)

Assuming that the mass of the ice cube is 1 kg, then the time required to melt the ice cube is:

Time (in seconds) = (30200 J) / (105 W x 1 kg)

Time (in seconds) = 287.6 seconds

Therefore, it will take 287.6 seconds for the ice cube to melt under the given conditions.
