Question

A pot of water is heated, what happens at a molecular level?

  1. The particles move at greater speeds
  2. The interparticle distance increases
  3. The kinetic energy increases
  4. All of the above

hintHint:

Heating causes temperature to rise

The correct answer is: All of the above


    As heat increases inside the pot, the temperature inside rises and the molecules start moving more randomly far away from each other and the kinetic energy also increases

    625 cal = ____ J

    Energy is the ability to do work which is measured in different units. Calorie and Joule are the units of energy which are proportionate to each other. This implies any change in the value of calories will change its equivalent value in joules. The relation between calorie and joule can be numerically written as : 1 calorie = 4.2 joules approx.
    Hence, 625 cal= (625* 4.2)= 2,615 joules.

    25 kcal = ____cal

    The kilo calorie is a measurement unit of energy. The symbol of kilo calorie is kcal.The kilocalorie is used in measuring the heating, calorific value or metabolizing foods. It equals to 1000 calories, or approximately 4.2 kilojoules. Therefore, 1 kcal= 1000 cal.
    so, 25 kcal= (25*1000)= 25000 cal.

    When sufficient heat is supplied to an ice cube

    When heat is applied to an ice molecule, the solid phase changes to the liquid phase and thus the ice is melted into water after applying heat. Heating a substance makes the molecules move faster and thus the heat energy breaks the hydrogen bonds that hold the molecules in the ice together thus resulting in melting of ice.
