Questions Related to phase change

Which of the following statement is wrong ?

physics the kinetic model of matter evaporation heat, internal energy and work phase change

  1. At room temperature evaporation of water is rapid as compared to ethanol

  2. Water is more viscous as compared to ethanol

  3. Liquid drops are spherical in shape

  4. Clothes are easily dried in dry day as compared to humid days

Show answer
Correct Option: A,B
Explanation:

A: At room temperature evaporation of ethanol is rapid as compared to water. Hence, A is incorrect. 

B: water is more viscous compared to ethanol, hence statement is true. 
C: liquid drops are spherical due to surface tension of liquid drop,hence statement is true.
D: Clothes are dried easily as it is less humid on dry day,hence statement is true.
