The Charles law states that pressure (P), volume (V) and temperature (T) is equal to a constant K i.e. PVT = k. From the above-given equation, we can infer that temperature is dependent on pressure and volume. Pressure in the cooker depends on the area of the hole in the lid, the bigger the hole in the lid, the lesser will be the pressure inside the cooker and hence temperature will be affected. Hence, 1 is correct. The more is the temperature of the flame the more will be the temperature inside the cooker. However the keyword “mainly” stops us from choosing Statement 2 as a possible factor. Hence, 2 is not correct. The weight of the lid has a direct connection in relation to maintaining enough pressure in the lid, heat release and heat-storing inside the cooker and hence can be linked with the temperature inside the cooker. Hence, 3 is correct. Therefore, option (d) is the correct answer.
