When I flipped through the recipe book, I realized that baking cake would take a longer time than baking muffins even when the temperature and the amount of mixture used is the same. So, I relate this with the first chapter i learn this year. <br />When the mixture is made into small muffins, the total surface area exposed to heat is greater. Hence, the rate of reaction increases.<br />Betul tak teacher? ^_^Raza Natasha Rahimnoreply@blogger.comtag:blogger.com,1999:blog-8310617777279304998.post-24419845505435281502012-02-05T17:43:29.404+08:002012-02-05T17:43:29.404+08:00for me is when we make two cups of coffee . we use...for me is when we make two cups of coffee . we use same size and quantity of coffee powder but different temperature of water . the higher the temperature of water the shorter the time taken for the coffee powder to soluble in water . err betul tak ?pari pari https://www.blogger.com/profile/06314404778796372070noreply@blogger.comtag:blogger.com,1999:blog-8310617777279304998.post-14099977665612687672012-02-05T17:27:19.267+08:002012-02-05T17:27:19.267+08:00teacher another one is, let's see when doughno...teacher another one is, let's see when doughnot dough is at warm place, the dough rises more quickly than in a cool one. betul tak teacher? and if we put salt/sugar in hot water, the salt/sugar is easily soluble in hot water. so it means that the higher the temperature, the higher rate of reactionhidayah sharin (5G)noreply@blogger.comtag:blogger.com,1999:blog-8310617777279304998.post-11601902869640905692012-02-05T17:22:49.737+08:002012-02-05T17:22:49.737+08:00when the temperature of the reactant increase,the ...when the temperature of the reactant increase,the kinetic energy of the reacting particles also increase...<br />betul x teacher?hehenur aqilah syarfa(5g)noreply@blogger.comtag:blogger.com,1999:blog-8310617777279304998.post-13148869001517871522012-02-05T17:19:56.150+08:002012-02-05T17:19:56.150+08:00*area*areahidayah sharin (5G)noreply@blogger.com
