Give few seconds for the water to stabilize to get more accurate results.
2. Look at the thermometer's reading perpendicularly.]]> 2019-01-14 04:54:06 UTC https://padlet.com/arunima_gpbhu/HYEg8QP/wish/320152157 https://padlet.com/arunima_gpbhu/HYEg8QP/wish/320152414 2019-01-14 04:56:35 UTC https://padlet.com/arunima_gpbhu/HYEg8QP/wish/320152414 https://padlet.com/arunima_gpbhu/HYEg8QP/wish/320152509 a) 22 degrees celsius

2. Increase the surface area of the water, maybe on a Petri dish, to allow for faster cooling.
3. Use a metal apparatus to cool the water, as glass is an insulator while metal is a conductor which easily heats up and cool down, allowing for a faster rate of cooling.
4. Perform the experiment in a cold room.]]> 2019-01-14 04:57:45 UTC https://padlet.com/arunima_gpbhu/HYEg8QP/wish/320152515 https://padlet.com/arunima_gpbhu/HYEg8QP/wish/320152522 (11A) 23 degrees celsius

(11B 1) The student should wait for a few seconds and then record the temperature because it takes time for the thermometer to stabilize

because water has a higher thermal capacity thus making its boiling/melting point much higher than other substances, this allows water to keep a cool temperature. (making it a good coolant)]]> 2019-01-14 05:00:15 UTC https://padlet.com/arunima_gpbhu/HYEg8QP/wish/320152724 https://padlet.com/arunima_gpbhu/HYEg8QP/wish/320152923 QUESTION 1 b up and down
