In which situation are the individual molecules moving the fastest ?

D) in a cup of boiling water

Explanation:

The question is incomplete. The following options are missing:

A) in a bowl of hot soup

B) in a glass of iced tea

C) in a glass of tap water

D) in a cup of boiling water

The four options involve liquids (option B probably includes some ice and option D includes steam water). As temperature increase, the speed of the individual molecules of a substance also increases. Ordering the options by temperature, from the higher to the lower, we get:

D) in a cup of boiling water

A) in a bowl of hot soup (its temperature is above ambient but not enough to boil its water)

C) in a glass of tap water (ambient temperature)

B) in a glass of iced tea (below ambient temperature)

Therefore, in option D the molecules move faster.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
