Which change in the temperature of a 1-gram sample of water wouldcause the greatest increase in the average kinetic energy of its molecules? (1) 1°c to 10°c (3) 50°c to 60°c(2) 10°c to 1°c (4) 60°c to 50°c

Option (3) is the correct answer.

Explanation:

Average kinetic energy is defined as the mean of all the energies present within the molecules of a substance.

Also, we known that relation between kinetic energy and temperature is as follows.

Since, kinetic energy is directly proportional to temperature. So, when there will be increase in temperature then this will also lead to increase in kinetic energy. Hence, average kinetic energy will also increase.

Thus, we can conclude that a change from to in the temperature of a 1-gram sample of water would cause the greatest increase in the average kinetic energy of its molecules.

what are the choices?

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
