Microwaving ice cubes

Description:

The data record the melting time of ice cubes when placed in a microwave at various settings. The ice cubes were made in 4×12 ice cube trays from town water, and left in the freezer for 72 hours.

A large bowl of water was heated by a Sharp Carousel microwave to ensure internal components were recently operating, so the first cubes microwaved were similar to later cubes. Then cubes were placed in a ceramic, room temperature bowl and heated in the microwave on a setting randomly chosen, and the time recorded to the disappearance of all visible ice.

Five bowls were used to ensure they returned to room temperature before reuse.

There are 48 observations on three variables.

Variables:
Sequence The sequence in which the cubes were tested; numbers from 1 to 48
Setting The microwave setting used. One of Off, Low, MediumLow, Medium, MediumHigh or High
Time The time taken (in seconds) for the last visible bits of ice to disappear
Data Quality:

There are no missing values.
