Consequences of thermal energy transfer
3 practice questions on Consequences of thermal energy transfer, with worked solutions and instant marking.
A student studies how insulation affects the rate at which hot water cools. She pours $200\,\text{cm}^3$ of hot water into a beaker, as shown in Fig. 3.1. She leaves it for a brief period. She then starts a stop-watch and notes the water temperature. This is the time $t = 0$.
