The table given below shows the amount of water in five identical beakers at the start of an experiment. It also shows the time required for the water in each beaker to go down by 20 mL What can we conclude from the table?
A
Water in beaker Q evaporates faster than in beaker P
B
Water in beaker T evaporates faster than in beaker Q
C
Water in beaker T evaporates faster than in beaker P.
D
Beakers R and S will have the same amount of water after 60 min.
Text Solution
Verified by Experts
The correct Answer is:
A
In beaker P. 60 mL of water took 50 minutes to reduce by 20 mL while in beaker Q. 60 mL of water took 30 minutes to reduce by 20 mL, so water in beaker Q evaporated faster than in beaker P. Water in beakers P and Q evaporates faster than in beaker T. After 60 minutes, beaker R will have 60 ml water while beaker S will have 70 ml water.
