Question

drink temperature (in °c) hot chocolate 50 milk 35 juice 40 water 15 list these drinks in order of kinetic energy, starting with the drink whose particles have the highest kinetic energy hot chocolate, water, juice, milk hot chocolate, juice, milk, water water, milk, juice, hot chocolate water, hot chocolate, juice, milk

Explanation:

Step1: Recall kinetic - energy and temperature relation

The higher the temperature of a substance, the higher the average kinetic energy of its particles.

Step2: Compare temperatures

Hot chocolate has a temperature of 50°C, juice has 40°C, milk has 35°C and water has 15°C.

Step3: Order by kinetic energy

Since higher temperature means higher kinetic energy, the order from highest to lowest kinetic - energy is hot chocolate, juice, milk, water.

Answer:

hot chocolate, juice, milk, water
