Question: (Describe Graph Shape)

GROUP DISCUSSION

INDIVISUAL ANsWER:
The graph shows a smooth curve decreasing from 85degrees to room temperature. 
(Water lost thermal energy to cooler surroundings) 
In the first 40mins, the temperature decreased steeply due to the big difference in the temperature of the water and the room temperature.
For the next 30mins,  when the temperature neared 30degrees, the decrease in temperature is less steep as the temperature of the water and the room temperature are reaching an equilibrium.
