Conduction is the process by which heat is transferred from the hotter end to the colder end of an object. The ability of the object to conduct heat is known as its thermal conductivity, and is denoted k.

Heat spontaneously flows along a temperature gradient (i.e. from a hotter body to a colder body). For example, heat is conducted from the hotplate of an electric stove to the bottom of a saucepan in contact with it. In the absence of an opposing external driving energy source, within a body or between bodies, temperature differences decay over time, and thermal equilibrium is approached, temperature becoming more uniform.

呀Sir教得好好， 每1分每1秒都學到野，而且我哋學校教得好好多，學校教啲嘢比較淺，好容易比一個錯覺啲同學仔以為自己識好多嘢，但係上完堂之後先發現，其實自己有好多技巧為或者概念其實未係好清晰，好鍾意配套好多，例如有小測試同埋有好多練習，可以即時比同學操練，了解自己嘅能力同不足之處！ 辛苦哂呀sir🥳開頭有個試下嘅心態黎補，補落發現其實TC係有總結到課程重點，俾到歷屆伏位同要注意的地方，仲有好多總結表，例如要背咩顏色之類，而且幾鍾意每堂個小測，可以逼到自己溫書去攞discount，都可以feel 到有教學熱誠，好關心學生，盡自己能力俾多d資源學生，睇重學生，比出面大補習社個d教幾十年，為教而教嘅老師好好多

The mock chemistry exam is an excellent resource for students preparing for their final assessments. It covers a comprehensive range of topics, effectively mirroring the structure and difficulty of actual exams. The questions are well-crafted, encouraging critical thinking and problem-solving skills. Additionally, the inclusion of detailed answer explanations helps reinforce learning and clarify misunderstandings. Time management is also tested, allowing students to gauge their pacing under exam conditions. Overall, this mock exam serves as a valuable tool for boosting confidence and enhancing knowledge, making it an essential part of any chemistry study plan. Highly recommended!

TC sir教得好好，課程內容好豐富，老師的教學能力超群，傳授 5** 實戰技巧，幫助制定清晰目標，掌握課題的考核重點，上課風趣幽默，幫助我們輕鬆取得高分，讓我可以在應試上更有信心，感謝老師用心的教導。

課程內容非常豐富, TC提供嘅資源都非常之多, 例如每個大topic都會有一另外仲有超級無敵難嘅WTH mock 本final note, 裏面個D細topic都有by-topic question bank, 同埋每個大topic都有兩份final mock, resources真係非常足料!

Despite the difficulty of the Mock Exam, I still strong understand and effort of TC team how to prepare it comprehensively. Not to mention almost the latest trend of DSE CHEM, but including brand new challenging question types. This brings me widen the horizon and more explosure. Whether the final result will be, I believe it is going to be a motivation to improve in such a limited time. Thank TC!

Tc sir的Mock十分高質，並且附送埋2024的Mock給我，真是太好了，由於我可以同時操到兩份高質的Mock,在真正的dse時在時間管理及答題技巧方面也進步了很多，我在這次Mock真獲益。

tc 份mock质量很高，有助帮助学生了解自己有哪些位置没有背熟 题目的种类也十分符合tip题模式 将重点可能会考的部分都汇集在一份卷之中 帮助学生备战dse

TC的課堂充滿了熱情和活力，讓我對化學產生了濃厚的興趣。不僅能夠將複雜的概念講解得淺顯易懂，還經常用有趣的例子來幫助我更好地理解和記住知識。

我非常感謝我的化學補習老師！他耐心教導，總能將複雜的概念簡化，讓我更容易理解，激發了我對化學的興趣，讓學習變得更加有趣和充實，真心感謝他的付出！
