Let\u2019s Get Started!<\/h2>\n
Are you able to accurately differentiate between the following terms?<\/p>\n
Conductors of Heat<\/strong><\/h3>\nThese are materials that allow heat to pass through them<\/span>.<\/p>\n\n- Good conductor<\/strong>: A good conductor of heat allows heat to pass through it QUICKLY<\/strong>.<\/li>\n
- Poor conductor<\/strong>: A poor conductor of heat allows heat to pass through it SLOWLY<\/strong>.<\/li>\n
- Better conductor<\/strong>: A better conductor of heat allows heat to pass through it FASTER<\/strong>.<\/li>\n
- Poorer conductor<\/strong>: A poorer conductor of heat allows heat to pass through it SLOWER<\/strong>.<\/li>\n<\/ul>\n
Insulators of Heat<\/strong><\/h3>\nThere is NO<\/span> such term.<\/p>\nWhy?<\/p>\n
This is because heat will ALWAYS<\/strong> be able to pass through both matter and non-matter.<\/p>\nThe only difference is how fast or how slow heat travels<\/em>.<\/p>\n\nRead Also:<\/h3>\n\n- How to Interpret Line Graphs on Heat Conductivity<\/a><\/strong><\/li>\n
- Heat Energy X Water Cycle: How Do Water Droplets Form?<\/a><\/strong><\/li>\n<\/ol>\n<\/div>\n
Conductors of Electricity<\/strong><\/h3>\nThese are materials that allow electric current to be conducted through them<\/span>.<\/p>\n\n- Good conductor<\/strong>: A good conductor of electricity allows<\/strong> electric current to pass through it easily<\/strong>.<\/li>\n
- Poor conductor: <\/strong>A poor conductor of electricity does not<\/strong> allow electric current to pass through it easily<\/strong>.<\/li>\n
- Better conductor<\/strong>: A better conductor of electricity allows MORE <\/strong>electric current to pass through it.<\/li>\n
- Poorer conductor<\/strong>: A poorer conductor of electricity allows LESS <\/strong>electric current to pass through it.<\/li>\n<\/ul>\n
Insulators of Electricity<\/strong><\/h3>\nThese are materials that DO NOT allow electric current to pass through them<\/span>.<\/p>\nLet’s Apply These Concepts On This Question<\/h2>\n

Many of my students also shared with me that the black object and the air surrounding the ice cube, which are poor conductors of heat, would not allow heat from the heater to be conducted to the ice cube.<\/p>\n
Hence, the ice cube should remain as a solid as it would take a long time to melt.<\/p>\n
Unfortunately, Option (1) is incorrect<\/strong>. In fact, certain parts of their explanation above, do not even make sense!<\/p>\nLet me share why with you.<\/p>\n
First of all, as mentioned previously in this article, a poor conductor of heat allows heat to pass through it slowly. It does not mean that heat from the heater will not be conducted to the ice cube at all!<\/p>\n
Given that hot air rises and cold air sinks, the air that gained heat from the heater would become warmer and rise to the top of the container.<\/p>\n
Thus, the air surrounding the ice cube would be warmer, causing the ice cubes to gain heat from the warmer surrounding air and melt.<\/p>\n
Given that 3 hours is a long time, the ice would have melted completely. As such, the answer to this question is Option (2)<\/strong>.<\/p>\nNevertheless, let’s run through the other two options:<\/p>\n
Option (3): All the water escaped from the set-up.<\/strong><\/p>\nIt was mentioned that the tank was \u201ccompletely sealed\u201d.<\/p>\n
Even if the ice has melted to form water and the water that dripped onto the heater has boiled to form steam, the steam would not be able to escape from the container.<\/p>\n
Option (4): All the water was collected on the heater.<\/strong><\/p>\nThe water that collects on the heater would gain heat from the heater to boil and form steam.<\/p>\n
Thus, it is not possible for water to have collected on the heater.<\/p>\n
Moving Forward<\/h2>\n
I hope this article has helped you to gain a better understanding of various terms used to describe some properties of materials, as well as how to analyse Heat<\/strong><\/a>-related questions.<\/p>\nWishing you all the best in your revision for the upcoming Preliminary examinations!<\/p>\n
