Very hot coffee! by Damian Boh https://padlet.com/bck1990/urkqq34qivha What would you do before drinking or touching a very hot cup of coffee to prevent yourself from being injured? Why? en-us 2018-01-05 04:59:03 UTC 2018-01-10 05:02:25 UTC hello@padlet.com PORTIA and other insignificant peasants😷 https://padlet.com/bck1990/urkqq34qivha/wish/220038018 before drinking, put a metal spoon in the coffee cup because metal is a good conductor of heat and as heat travels from a hotter region to a colder region, the cooler metal spoon will gain heat from the hotter coffee and hence the temperature of the coffee will drop (?)]]> 2018-01-10 04:56:48 UTC https://padlet.com/bck1990/urkqq34qivha/wish/220038018 https://padlet.com/bck1990/urkqq34qivha/wish/220038040 Before drinking : blow the coffee to cool it down 
Before touching : wrap the cup with cloth to slow down transfer of heat ]]> 2018-01-10 04:57:12 UTC https://padlet.com/bck1990/urkqq34qivha/wish/220038040 group at the back :-) https://padlet.com/bck1990/urkqq34qivha/wish/220038108 before drinking, blow the coffee to let it cool down. the temperature of our breath is lower than the temperature of the coffee, hence the coffee will lose heat to both our breath and the surroundings.

before touching, use a cloth to hold the cup. the material of the 
cloth is an poor conductor of heat and will slow down the heat transfer from the hot cup to our colder hands.]]> 2018-01-10 04:58:05 UTC https://padlet.com/bck1990/urkqq34qivha/wish/220038108 The group that sits in front https://padlet.com/bck1990/urkqq34qivha/wish/220038114 Before drinking or touching the cup, we will leave the cup of coffee to cool and lose heat to the surrounding sthto that the temperature will be lowered.]]> 2018-01-10 04:58:12 UTC https://padlet.com/bck1990/urkqq34qivha/wish/220038114 liuyingswifi https://padlet.com/bck1990/urkqq34qivha/wish/220038155 add ice cubes inside and wrap the cup w a wet cloth :-)]]> 2018-01-10 04:58:59 UTC https://padlet.com/bck1990/urkqq34qivha/wish/220038155 Athena the grp https://padlet.com/bck1990/urkqq34qivha/wish/220038176 blow on the drink and stir the drink to increase the surface area so more heat will go away.
