Question

A student did an experiment with ice. A beaker of ice was placed on a hot plate for 30 minutes and its temperature was recorded after every 5 minutes. The table below represents how the temperature and state of ice changes with time.
Time from start (in minutes) 0 5 10 15 20 25 30
State of matter in beaker ice water P water Q steam steam
Temperature of matter in beaker (in ° C) 0 0 50 80 100 100 142


What do the labels P and Q most likely represent?
both P and Q represent ice
both P and Q represent water
P represents ice and Q represents steam
P represents steam and Q represents ice

Answer 1

From the table, we can see that  P and Q represent water. (Option B)

What does P and Q represent?

We know that the liquid range of water is 0 - 100 degrees Celsius. Within this temperature range, water exists as a liquid substance.

Looking at the table we can see that the temperatures of P and Q are 50 and 100 degrees Celsius respectively hence both P and Q represent water.
