Classmate Matthew says that if all the molecules in a particular liquid had the same speed, and some were able to evaporate, the remaining liquid would not undergo cooling. Do you agree or disagree, and what is your explanation?
The statement from Matthew “if all molecules in a particular liquid had the same speed and some were able to evaporate , the remaining liquid would not undergo cooling.” is true or false , explain your reason .
Answer to Problem 29A
The statement is false as the speed will be same only when the evaporation rate is equal to condensation rate .
Explanation of Solution
The statement is false .
To make the speed same for all molecules the evaporation rate should be equal to the condensation rate .
Thus, as much the liquid evaporates as the liquid should condensed.
Conclusion:
The statement is false as the speed will be same only when the evaporation rate is equal to condensation rate .
