Question

Knowledge of concepts is not enough for a learning experience to be meaningful.
We should also understand how the concepts we learned on intermolecular
forces can be applied to real life situations to get the most out of what we
learned. Let us look at this simple situation that will help us realize the
advantage of fully understanding intermolecular concepts.
Situation:
You are asked by your mother to cook pork nilaga. You have only an ordinary
kettle to use for cooking. She even reminds you to save energy because we are in a
state of pandemic due to covid-19. Saving resources nowadays is a must because
we are not sure of the world’s economy. As a student of Physical Science and with
your knowledge of properties of matter in relation to intermolecular forces, how are
you going to perform your task in such a way that energy is not wasted?

Answer 1

Answer:

I will save energy by cooking in middle flame and cooking fast

Answer 2

While starting to cook pork nilaga I will keep in mind a few things which would help me save energy

1)  Pre-cooking  preparations

I would make sure that I have chopped all the vegetables and have my cooking essentials ready before turning on the stove .

2) Covering with the lid

Covering the pan after adding ingredients and vegies I would cover it with the lid as a low temperature on stove while cooking would help to decrease the energy use up to 66 percent.

3) Turn off the stove before time.

The kettle will retain the same temperature within  itself, investing more energy would be a wast. The food will continue to cook until the unit cools down.
