Physics - Heat & Thermo Question with Solution | TestHub

The temperature ( $\theta$ ) versus heat transfer ( Q ) plot for two substances A and B is given in the figure. If some quantity of substance A in liquid phase at temperature 30°C is mixed with substance B at 20°C then the temperature of the mixture will be. (Given that boiling point for substance A is more than $30^{\circ }\mathrm{C}$ )
